..I'm a taxi driver on the motorway ..
Your a taxi driver, you get a warning light indicating low oil pressure, you hear a bang and knocking noise (big end bearing?), you continue onto motorway anyway, struggling to maintain comfortable cruising speed the engine seizes, you are in the fastlane and desperately try to make the hard-shoulder, the klaxon of the HGV sounds in you ear as you thank your blessings that you are not at 36,000ft!
