The Richmond Park 3-Lap Challenge

^ Same here. I just go and do laps. If a car or scooter has the temerity to "drive so slow" (probably somewhere at or near the proscribed limit maybe, quelle horreur) then I just have to live with it, trying to blast my way through will eventually only end up badly for me.

If you want to do fast RP laps then you've two options:
a) Wait until summer and sunrise is before 5am and get in there early, far less traffic at those times
b) Fit some good lights and use the park after dark when there are no cars (mind the joggers and the wildlife though).

Video shows so quite a few examples of poor decisions:

• Close overtakes of other cyclists (not everyone is used to group riding and close overtakes) 1:08 for example
  
• Undertaking cars (although on the approach to some of the car parks this is sometimes the least worst option, but not at those speeds)
  
• The Kingston Gate roundabout approach. Luckily Kingston Hospital is only a few hundred yards away.
  
• The Robin Hood Gate roundabout approach. Undertaking between a car and a pony at the side of the road. Nice work. All you need to do is startle that pony and a small child gets thrown to the ground (Won't someone think of the children!). Give animals more space than that when passing them.
