Evidence?
All the stats show that actual incidents involving cyclists have been on a downward trend for years, both in absolute numbers and relative to the amount of cycling that goes on. Those same statistics show that cycling is very safe and that most of us will never be involved in a serious incident with a motorised vehicle. You need to ride for 100,000 hours (riding for 11 years, round the clock, 24 hours a day, 7 days a week, 52 weeks a year) before you can expect to be involved in a serious incident.

What
has changed is that forums like this one, online news services like the BBC article that prompted this thread and throwaway comments like the one made by the rider in the original article magnify the perception of danger.
All of which says nothing about driver attitude - and my anecdata is that driver attitude has significantly improved since I started riding regularly as an adult 30 years ago. Probably because there are far more cyclists on the streets I ride on than there were then.
