A novel idea. Had too much to drink? Get someone else to drive you home. Call the number and someone turns up on a small folding bike which they put in the boot of your car. They then drive you home, unload their bike and drive away. It's been done before and is usually quite expensive, but is it any more expensive than being fined for drink driving and possibly losing your license?
