punjabi taxi 

the empty vehicle driven by a Punjabi Taxi-man at 2 am around stevenage, hitchin and luton, with little regard for speed limits, the highway code or safety of other road users, while on their way to a fare.

The expression is quite common in stevenage where it originated, due to the large amount of Taxi cabs driven by people of asian origin.

Note, that even non-asian taaxi drivers can be refered to this way if they are driving in the manner describes above.

"shall we walk or take the punjabi taxi?"
