The EV gets to just run everything backwards when you step on the brakes. This won't stop you, but it'll make a huge difference to the remaining force needed to stop you, so it massively reduces wear on brakes and (which is why they did it) increases the effective range of the vehicle. And since they aren't worn out, the brakes need maintenance far less often. Driven gently the brakes on a EV might last its useful lifetime.

You can't do this with ICE, if you put diesel fumes in a compression chamber and pump the cylinders up and down, it doesn't turn back into diesel fuel, combustion isn't symmetric, so you need to actually have brakes.
