As drivers I'm sure we have all experienced the dreaded understeer. Carry too much speed and you're just a passenger in your own car as that crash looms just milliseconds away. Unlike oversteer which with the right circumstances can be ridden out, there seriously is no way to get yourself out of a high speed understeer. Take the Lancia Delta Integrale in this video for example, this is why understeer is a drivers' natural enemy.
