the problem of drink driving has been solved loing ago
most cars now have cup/tin holders
i may be wrong but i think there is a £50 fine for using a mobile phone while driving and a £200 rerward for reporting a drink driver
if you are behind a drink driver you can report him using your mobile and get £200 but deduct £50 for using the mobile to report them
total proffit £150
who says crime dosnt pay lol
