As someone who both walks the prom and cycles it, I can assure you that as always, there are two sides to every story. For every speeding idiot on a bike, there are double the number of walkers who, having seen you, very deliberately step out in front of your path at the last moment. What point they are trying to prove, I have no idea. Other walkers can get very abusive indeed - even when you are nowhere near them.
Reckless and belligerent mobility scooter riders, now that's an issue........
