I'm not a fan of electric power steering on these new cars i.e Toyota that use it but they have a weird system that has been known to fail and cause problems, like when we do a wheel alignment vsc and trc lights come on and have to recalibrate steering. But Toyota uses some thing so steering sensitivity on highway is reduced and then in car parks it turns the lower half of the steering shaft more so than the top that you are actually turning, but I doubt you would be using anything like this.
