> disc brakes still function much as they did 10 or 15 years ago (and wear out) Actually, regenerative breaking means they last quite a bit longer.

  Brake pads are cheap, discs aren't very cheap but are still reasonable. A regenerative braking system? I'll bet that's a lot more expensive.

    Shouldn't be actually. The regenerative braking system on an electric car is just the regular drive train. The energy just flows in reverse. The wheels drive the transmission that drives the motor that charges the battery.

    In an electric vehicle, regenerative braking is free. It's just the motor turning kinetic energy into electric energy, rather than the other way around. There aren't really any extra parts or systems involved.
