Really? Traction control is all about putting the power down to the
wheels with the best grip. Do cars really implement this by applying the
brakes to those wheels which you don't want power transferred to?

Yes, and they cut the power, too. See

Slightly scary is that some systems will *apply* power to maintain
directional control, even though the driver is requesting full braking.

One of the attractions of a high-end car is that the accelerator is a
"speed pedal", but the quid pro quo is that the brake is a "stop pedal".
