Except their weight which leads to insane amounts of energy transfer and also none of the intrastructure, like guardrails, is built to handle that much weight so low down.

The way to safer is to reduce the amount of cars.

    First time I ever heard about guardrails having issues with EVs. Do you have a source for that?

    Also the comment was about the fire risk, which the article was about.

    It affects more than the guardrail situation as well. Any collision with a car laden with extremely heavy batteries as low to the ground as possible has inertia and force that was not calculated into road safety systems originally.

    This can be corrected, but the first step is recognizing and accounting for it. Which seems to upset people for reasons I cant comprehend.

    But as the other guy said, the safest systems are the ones with the fewest cars on the road in general.

    Next best thing to improving public transport to reduce the ammouny of cars would be reducing the size of cars, thus in large part negating the weight issue.

    But like you said, nothing beats just having fewer cars on the road.

    EVs weigh similar to similar ICE vehicles.

    Yeah, no.

    This is a golf compared to an id.3. Two very comparable vehicles. The id.3 weighs 41% more. Don't get me wrong I'd love to be able to get an id.3 but all we get in the states are these horrible SUVs. That said EVs do still suffer a major weight penalty that comes with its own issues.
