Zwift unveils new Crit City course

If you're not trying to escape from wild animals, what would be the advantage of putting a tent on top of a car, rather than setting up a similar tent on the ground? Seems rather unnecessary to me - even if the price was comparable, I would choose a ground-based version.

V v tempting.

"you can’t pass a law saying it’s illegal not to have a speedometer if you’re going to go above the speed limit." I don't think this would be a good idea, nor even speed limits (and presumably mandatory speedometers everywhere) ... ... but is there any theoretical legal impediment to that? Or even simply enacting a law that cyclists are not permitted to ride faster on roads than the motor vehicle speed limit (or some other limit) and leaving it up to cyclists how they go about complying with that? (Not a lawyer not a legal theorist though...)

What has KE to do with it? If you are hit by a large object you don't absorb all its KE. Being hit by a car is no better than being hit by a bus at the same speed. What matters is how much acceleration you experience.

@Robert Hardy 20mph isn't as fast as you seem to think, this 57-year-old-not-that-fit rider can easily achieve it on the flat in still conditions and most averagely fit people can on a decent bike. The argument that it wouldn't be a problem to impose speed limits on cyclists because those who can achieve 20mph already have speedometers is an entirely specious one, firstly as I've said a huge number of people can achieve 20mph, not just Garmin-obsessed racers, and secondly you would have to make speedometers compulsory for everyone on a bike, you can't pass a law saying it's illegal not to have a speedometer if you're going to go above the speed limit. How many cycling incidents are caused by supposedly excessive speed? It wasn't a factor in this case, the cyclist would still have hit her if he'd been doing 15mph or even 10mph. Charlie Alliston was under the car speed limit. It's a non-issue and only of interest to those seeking yet another stick with which to beat cyclists.

(Usual reference to speed being the major issue as kinetic energy goes up with the square of velocity / much greater braking distances required etc)

@mdavidford steady on - an 80kg cyclist on a 20kg bike would only need to be doing a little over 89mph to have the same kinetic energy as a 2 ton car at 20mph. So same ballpark, really...

Yes, although it may be telling us as much about decision fixation as it is about the impact of such statements. By asking them about their plans before viewing the adverts, they primed those who said they would consider an SUV to ignore or rationalise away information that pointed against that decision. Ideally, they would have had additional cohorts that were not asked in advance and therefore not committed to a position, for comparison.

"in --substantial-- slight excess of a speed limit considered to offer reasonable safety to vulnerable road users *from two tonne metal boxes*." FTFY

I think we have forgotten that cars do way more damage and we still haven’t got a comprehensive-lasting solution to deal with dangerous drivers
