In my experience Bristol has been a nut-house on its roads for at least the past 40 years! That applies to everyone, drivers, riders and walkers. Regard for the safety of self and others is low, as is respect for road rules and law.
I don't go there often now, but my experience would suggest summerdays figures are about right. They're also about right for drivers.
Every time I visit I see some of the worst driving and worst cycling I've seen anywhere. The riding isn't helped by Bristol having wide and often straight roads with steep hills on them, which encourages inapropriately fast riding. (Who am I to criticise if I look back a few decades!)
The cycling facilities are definitely better than they used to be, and with good management the £11m will do a lot of good. Good, dedicated, cycle routes from the park and Ride sites, with free parking when ride is on a bike, would be a good start. User482' north south route would be a good move. Again it needs a dedicated cycle road. Unfortunately we don't do dedicated cycle roads in Britain, and if we did they probably wouldn't have the smooth tarmac found elsewhere.
