For me “How long could I get away with driving like an ABSOLUTE ASSHOLE all the time before I lost my licence or had an accident.” Speed limits, red lights, stop signs… forget them all. Every day I have to drive sensibly and obey the law because without my licence I dont have a job, and every day I see at least one person driving like an absolute moron and I wonder…
