[python] Re: one stubborn guy

Olaf

In the past, people said that front wheel drive cars are evil things...
Today rear wheel drive cars are the exception. When the first microwave
ovens began to sell, some people have said that it may cause cancer... The
guy for whom I've built my first Python, asked me if the negative trailing
is a safe thing... I've said him that a truck with its trailer is pivoted,
the angle of the pivot is 90 degrees and the classic "L crash" (when the
trailer tries to surpass the truck) is a rare event...
