I've upset a few drivers because they didn't think I was making fast enough progress, but I try to keep calm and don't react or do anything to upset them further so thankfully I've never been the subject of a road rage attack. You'd probably like driving in my area because our council decided to impose a 20MPH speed limit across the whole borough, so driving is quite leisurely, but it upsets some types of road users and I've been overtaken in quite dangerous ways, one day there's going to be a fatal head-on collision caused by impatient drivers.
