Electric vehicles are heavier, which can increase the risk of death and serious injury in a crash
Electric vehicles (EVs) are heavier than traditional cars, and this additional weight can increase the risk of death and serious injury in a crash. The National Transportation Safety Board (NTSB) notes that EVs may weigh as much as one-third more than comparable gasoline-powered vehicles. This extra weight translates to more momentum, which means greater force is applied in a collision.
The weight difference between EVs and traditional cars can have significant consequences in the event of a crash. A study found that a 1,000-pound weight difference between two vehicles results in a 47% increase in the fatality risk. The batteries in EVs can add a significant amount of weight, with the battery pack of a GMC Hummer EV weighing 2,900 pounds, which is roughly the weight of a typical Honda Civic.
The heavier weight of EVs can also increase the risk of rear-end collisions, as heavier vehicles require longer stopping distances, especially in emergency situations. Additionally, the increased weight of EVs can pose challenges for safety infrastructure such as guardrails, which may not be designed to withstand the force of a heavy EV in a rollover accident.
While the weight of EVs can increase the risk of serious injury and death in a crash, it is important to consider other factors as well. EVs have high horsepower ratings and race-car-like acceleration, which can catch drivers off guard and lead to accidents. The silent operation of EVs can also be a safety hazard, especially at low speeds, as pedestrians may not be able to hear the vehicle approaching.
In conclusion, the weight of electric vehicles is a significant factor that can increase the risk of death and serious injury in a crash. However, it is important to consider the broader context of EV safety, including the unique challenges posed by their lithium-ion batteries, the potential for fires or explosions, and the evolving nature of EV technology and safety regulations.

The batteries in electric vehicles can catch on fire or explode, causing severe damage and injury
Electric vehicles (EVs) are powered predominantly by lithium-ion batteries, which have been known to spontaneously overheat and explode even when in a compact form in consumer electronics. This is known as "thermal runaway", a chain reaction that can cause a battery to overheat, catch fire, and explode. While the chances of this happening are slim, it is a unique risk that does not exist in vehicles without these forms of advanced driver assistance.
The potential for battery fires or explosions in electric vehicles can cause severe damage and injury. For example, if an electric vehicle’s battery catches fire after a crash, the vehicle manufacturer could be held liable if the fire was caused by a defect in the battery. In such cases, the company that produced the battery may also be named in a lawsuit. Additionally, electric vehicles contain complex electrical systems, and a malfunction in these systems could lead to accidents.
Furthermore, electric vehicle batteries take a long time to cool down and there is a risk of reignition, even days later. This means that first responders and recovery teams must be aware of the potential for electric shock or a secondary fire. Unlike gasoline-powered vehicles, electric vehicles do not have widely known safety measures such as reinforcement, shutoff valves, and other safety measures that reduce the risks of fuel igniting or exploding in most collisions.
While electric vehicles are less likely to catch fire than their gasoline-powered counterparts, the fires caused by electric vehicle batteries are more challenging to extinguish. This is due to the high energy stored in the batteries, the chemical composition of the batteries, and the protection the batteries have from the elements. As a result, some firefighters are receiving special training to extinguish the extra-intense EV flames.

Electric vehicles are quieter, which can be deadly for pedestrians who cannot hear them approaching
Electric vehicles (EVs) are generally known for their environmental benefits and advancements in technology. One of the notable features of EVs is their quieter operation compared to traditional internal combustion engine (ICE) vehicles. While this reduced noise can have public health benefits, it also raises concerns about the safety of pedestrians who may not be able to hear approaching EVs.
The silence of EVs can be particularly dangerous to pedestrians, especially when these vehicles are traveling at low speeds. Pedestrians are accustomed to relying on engine noise to gauge the presence and proximity of approaching vehicles. With EVs, the absence of this auditory cue can make it difficult for pedestrians to track the vehicle's movements and increase the risk of accidents.
This issue has gained attention in recent years, with studies exploring the potential risks associated with the low noise levels of EVs. One such study conducted in Málaga, Spain, examined the perceptions of workers and pedestrians who come into contact with EVs during their daily routines. While some participants acknowledged the environmental benefits of EVs' quiet operation, they also recognized the potential dangers, suggesting that extreme caution is necessary when driving or walking near roads to avoid crashes.
The unique crash hazards posed by EVs have led to concerns among owners, rescue workers, and the general public. In the event of an accident involving an EV, determining liability can be complex, especially if the crash was caused by a malfunction in the vehicle's electrical system or battery. As EVs continue to gain popularity, it is important for all road users to be aware of the potential risks associated with their quiet operation and take extra precautions to ensure the safety of everyone on the road.

Electric vehicles have faster acceleration, which can cause drivers to push too hard on the accelerator and jerk forward
Electric vehicles (EVs) have faster acceleration than traditional cars, which can cause drivers to push too hard on the accelerator and jerk forward. This "overtapping effect" has been identified as a potential cause of accidents, as drivers may not be accustomed to the quick acceleration of EVs, especially when transitioning from gas-powered cars.
The instant torque produced by EVs allows them to put all their power into acceleration from the start, unlike gas-powered vehicles that need to build acceleration. While early statistics on EV use don't indicate that rapid acceleration is a major cause of crashes, it is easy to envision scenarios where an inexperienced or careless driver could make this mistake.
The AXA Switzerland study found that drivers of electric cars caused 50% more collisions with damage to their own vehicles than drivers of gas-powered cars. The researchers attributed this to faster acceleration, which can lead to more accidents, especially for those new to driving EVs.
However, it is worth noting that EVs also have advanced safety features that can reduce the risk of accidents. For example, regenerative braking uses electricity to slow down the vehicle, reducing wear and tear on the brakes and making them less likely to contribute to an accident. Additionally, EVs have a lower center of gravity and a stronger frame, reducing the risk of rollovers, one of the most dangerous types of accidents.
While the faster acceleration of EVs can be a factor in accidents, it is important to consider the overall safety features of these vehicles. As EV technology continues to evolve, addressing concerns about safety in collisions is crucial to ensure the well-being of drivers, occupants, and pedestrians.

Electric vehicles have advanced safety features, but issues with software, batteries or charging systems can impact liability
Electric vehicles (EVs) have several advanced safety features, but issues with their software, batteries, or charging systems can impact liability in the event of an accident.
One of the critical safety features of EVs is their electric propulsion architecture, which allows for a lower centre of gravity and reinforced frame, reducing the risk of rollover and other accidents. The crumple zones and impact-absorbing materials in EVs can be designed more effectively without the constraints of accommodating an internal combustion engine. Additionally, EVs often have airbags positioned in the floor, offering better protection during side-impact collisions. The rearview camera is another safety feature that enhances visibility and helps drivers see pedestrians and vehicles behind them.
Regenerative braking is another safety innovation in EVs. This system uses the electric motor to slow down the vehicle while directing charge back into the battery. This reduces wear and tear on the brakes and enhances control and stability during sudden stops or emergency braking. Advanced driver-assistance systems (ADAS) are also becoming standard in EVs, including features like adaptive cruise control, lane departure warnings, and automated emergency braking, all of which help prevent accidents and reduce injury risks.
However, issues with software, batteries, or charging systems can offset these safety advantages and impact liability. Software issues, for instance, can render an EV undrivable until a software update is installed. This problem is unique to EVs and can leave drivers stranded, requiring a tow to the dealer. While software updates can be easily monetized, the software is tied to critical hardware, and any issues can have severe consequences.
Battery-related issues in EVs can also impact liability. Battery combustion is a significant concern from a fire and safety perspective. Additionally, charging problems are common, with electric car owners experiencing challenges in 20% of public charging sessions, according to a Consumer Reports survey. These problems can include broken plugs, plugs blocked by ice, or other connection issues. While owning a home charger can mitigate these issues, it is not an option for everyone.
In conclusion, while EVs offer advanced safety features, problems with software, batteries, or charging systems can impact their overall safety and complicate liability determinations in the event of an accident. Addressing these issues is crucial to enhancing the safety profile of electric vehicles.
