The problem is (even with people just turning 90 degrees) that they don't know how to do it. They pull too tight initially, ease up as they accelerate as the lateral forces increase, then have to pull tight again if they are to stay in the same lane. In reality they don't do the third step because either a) they'd have to slow down, which they don't want to do or b) have to turn tight and they don't like the increase in lateral G forces, so they just drift into the outboard lane in a pseudo-Euler spiral without a care in the world.
