Like any form of transport, the inconsiderate and antisocial element give the majority a bad press. The adult cyclist who jumps red lights, weaves through pedestrians at speed while using the footway and generally sticks two fingers up at anything delaying his progress deserves to have a bike pump shoved up his rear end. Perhaps it's more of a city thing where it's worse
Round my way we have a reasonable network of cycle lanes on the carriageway through the town, but there's no way that I'd let my kids use them (and I seldom use them either). Too many of the drivers who share the same carriageway are going way over the 30mph limit and as they pass any cyclist brave enough to use the lanes, they drive very close which often causes a problem for the cyclist. There's been more than one occasion when I've felt a lorry wing mirror or load brush past my head while cycling (getting hit by something that solid at around 40mph is going to make a mess). At other times it can be air turbulence as HGVs speed past at nearly 50 in a 30 limit that pulls you across into danger....... (where are the coppers with speed guns when you need one....

)
Nah.... on balance I'll use the footway when I can even though I know I'm not meant to.. I've been to too many fatal RTAs where it's cyclist vs car/lorry/bus and the driver has been at fault to take the risk. There's only been one fatal accident that I've attended in my area involving a cyclist vs pedestrian (7yr cyclist rushing back home in blind panic to get to mum after his brother breaks arm in playpark, collides with 90yr old lady coming round the corner of a footpath who falls and hits head on wall.... hardly compares really)
If you have an accident on the road as a cyclist you'll be lucky not to be spread along the carriageway by passing vehicles. If you have an accident on the footway the worst that will happen will be cuts and bruises.
But then again, I'm one of those cyclists who goes at walking pace if there are other pedestrians using the footway.... :lilangel: .
As for those mobility scooters.....

Bloody lethal.... Meant to be restricted to 4mph but I swear the majority are capable of 10mph plus... They can nip your ankles.... A fella I see around town most days seems to have some sort of sports version of the thing with big chunky wheels on! Always seen riding it with a fag in his gob......
