Enough what though?
Cyclists putting themselves in the danger hotspot alongside HGVs and large vehicles? because it seems to me that's where most of the deaths are occurring.
"There's a big gap, I'll pull out left before he even moves off, he can't miss me here, he's seen me, he's seen me, he might not have, no he has, he's seen me. But he might not have, hmm true, tell you what let's not take the chance. It's like all those deaths we hear about and those protest march rides, just this situation, nah, plenty of time I'm not one of those fools, he's seen me I'll be ok....."
Have these protesters sat in a truck at a demo day and seen the drivers view?
There's a lot of visability, still some blind spots true, but it's not bad. The driver will check and check again and move off, but big vehicles move off slowly, how many riders then chance it? The truck may move off slowly but once turning the vehicle length closes that gap very fast.
Driving a two lane roundabout alongside a truck, well I'm in my rights to use the inner lane, and that truck should stay on his side of the road it's the law, but I know it won't so you know what I'll not try to pass a turning truck. The guy driving in front does though, and look the trailer has swiped his car up the roundabout, 1st thoughts - 'kin idiot why pass a truck?
I drive a lot and every day without fail multiple bad drivers will do something that could cause an accident, but I look out for them, I pay attention, they are doing something wrong so I don't put myself in the dangerous situation, I'll not change their habits so I'll not risk myself.
Two vehicles should not be side to side occupying the same lane, especially when turning, simple isn't it?
Cyclists should sit in the queue of traffic, two abreast. So you'll pull off slower than the car behind and piss him off, but at least you're riding by the law. And you know what he'll have to just drive slower, a tractor wouldn't pull of quickly either.
Oh and look having patience and riding this way hasn't put the rider in the door zone/pothole zone/drainage grid zone/road litter zone either.
Commuting by bike may be quicker where there's less traffic or dedicated cycle paths, traffic is traffic and on the roads and cyclists are part of it too. The risky driver, weaving like a knob and speeding to miss the reds will be the cause of many accidents and what will the law say "traffic is bad at this time, you should've left early and allowed more time for your journey, you know how long your commute route takes, you're nicked."
So what do I propose, change the simplest thing, cyclists behaviour and road use. The knock-on effect will win out.
Everyone nowadays expects to be looked after by someone else.
