Last week I read that significant plastic is released in nature by tire wear. Electric cars are often heavier then their gasoline equivalents. I wouldn't be surprised if they wear faster and pollute more microplastics.

This I read by the way from the book "The hidden impact". There's a digital version in English on the website https://babetteporcelijn.com/en/. It has a lot of data that tries to help people to make sustainable impact that matters.

Note that I'm not against electric cars at all. I'm only talking about pollution of microplastics. Not pollution in general.

Of course it's hard to tell if people downvote because they disagree with me or because there are actually falsehoods in my comment. If it's the latter it's either: 1) electric cars are not heavier, or 2) tire wear due to additional weight is neglectable. Please, correct me if I'm wrong. Perhaps it's my filter bubble, but I only find articles that support my statement [2]. I quote:

"For energy use, the weight is less of a problem than for gasoline cars. They waste the increased energy used to accelerate the higher weight. But the momentum of an electric car lets you return energy to the battery as the car slows. The heavier the car, the more energy it takes to accelerate—but the more you return to the battery commensurately through regenerative braking.

Of course, if you pay six figures for a high-performance electric car (think Tesla Model S P100D) and use its capabilities, you should expect to replace your very expensive low-profile tires every 15,000 miles or so. That's par for the segment."
