Earlier quoted context omitted.
I've been seeing a lot of anti-electric stories recently, even here. A lot about how Hertz has been selling their electric cars (mostly unrelated to them being electric, but because they see a lot of scrapes and scrapes are costlier for them to fix on the electrics they have), about how the market is cooling down, etc. Seems like some interests are threatened by the prevalence of electric cars.
You can't engine-brake with an electric engine (with a combustion car, downshifting will force your car to be slower when going downhill, basically) so in mountain regions with ups and downs there's way more braking leading to massively increased tyre wear.
Second, huh? How does engine braking reduce tire wear at the same speeds? Brakes do not contact the tire. It reduces brake wear...
Gentle braking reduces tire wear but that's possible with either mode.
