As a person I'd never lend a car to, Tiff is one.
On a vintage three wheeler, with the same size front and rear tyres, there is a way out of understeer. You open the throttle further. I've got no idea if this works on a five speeder, and the public highway is not the place to find out. It's also very counter intuitive.
Anyone trying this, I'm not recommending the manoeuvre, merely observing.
