New tires every 7k miles? Electric cars save gas; tire wear shocks some drivers

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.

Can you please explain the mechanics of this? Engine braking, ignoring a semi jake brake style, is using the weight of the engine to slow the vehicle down. The mechanics of an EV using regen in my head seems pretty similar. You are generating electricity which is creating resistance, similar to how turning the engine without using petrol is creating resistance.

Every 30,000km seems really often to become completely worn

If they’re reasonably soft semi-performance tyres the figure doesn’t seem surprising
