Is this EV AC vs DC for dummies? Or EV lessons from a Power Wheels?

From my reading on here, AC electric cars have regenerative cycle built in. However, I know for a fact a DC motor can generate electricity. So why don't more people take advantage of this? Is it simply too difficult to make a DC motor controller that can also have regen braking?

I was thinking these thoughts as I pushed my 2 year old around on her 6 volt power wheel. If I pushed her while she was pressing the go button for the motor, there was considerably more drag than if she let off the button and opened the circuit to the motor.

Can those who know explain the complications of using a DC motor in an electric car and wiring in some sort of regen braking?
