Radio 4 one sided discussion on Richmond Park event cancellation
Radio 4 0845 21/08/2024.
Can’t believe what I just heard. Completely one sided discussion. Neglected to mention that the cyclist(s) involved in the tragic death of a pedestrian were found to be completely innocent of any wrong doing.
As for not being able to judge if iyou have time to step off the pavement because a bikes speed is hard to judge - if any doubt exists whatsoever - don’t….

Didn't happen did it? They came into my shop a couple of years back and said it was "on the way", but never heard anything more.

Very parochially, I've still not forgiven Pearson's for abandoning their roots by leaving Sutton.

edit : made a complaint on the bbc site.
You don't need to judge the speed of a cyclist to figure out if it's safe to step out in front of it - just go by how far away they are and treat them like you would a driver. IIRC, the Richmond Park collision had the pedestrian step out only 2m in front of the cyclist which would be reckless for just about any speed of cyclist. The whole focus on the cyclist's speed and "racing" is just a diversion as neither is at all relevant.
Absolutely, I did the calculation at the time and worked out that the extra reaction time at that distance for the motor speed limit of 20 mph instead of the cyclist's alleged 30 mph would be seven hundredths of a second (0.22 vs 0.14) and neither speed would give sufficient time for a reaction.
(It was Regent's Park btw)
I roughly worked out the speed at which a cyclist could stop within 2m and it was about 3mph or so.
That can't be right - didn't the police experts in the Alliston/Briggs case prove that a bicycle can stop from 153 mph in less than 30cm? (or something - I may be misremembering…).
