>In the UK, to "overtake" a car is to "pass" it. If you overtake on the nearside then this is colloquially known as "undertaking". And it's an easy way to end up in the care of "undertakers" (morticians).
On a related note... "podvodač" (underguide, or rather, sub-leader) is the official term for a pimp in Serbian et al.
