Yep, rypt is right with this one![]()
Apart from the one person who argued against I doubt you'd get any others to agree with his point of view. Cyclists are bound by the rules of the road and thus should follow them and just like car drivers some will some won't - or more realistically most will break the law when they think they can get away with it or it is deemed to only be a little infraction of the law like the aforementioned 35 in a 30 limit.
You can get some cyclocross bikes with disk brakes and quite possibly some road bikes too. Although if calipers are good enough for Tour De France riders they should be sufficient for most mortals who can't hope to reach such speeds admittedly a cleared course is different to the roads of a city.
Cyclocross bikes can have hydraulic disk breaks for one reason: They are clear of the mud and thus don't reduce in performance by getting clogged with mud.
For road bikes they aren't any better than good dual caliper U breaks. They weigh more as well so start to defeat the point of a road bike as in it should weigh as little as possible. Secondly the main problem is surface area of the tyres. 23mm wide tyres don't have a lot of contact with the road (hence the increase in speed) so when breaking hard locking the wheels up will happen long before the breaks fail due to heat build up or whatever.
There is a simple answer to this: Ride within the conditions of the road. Doing 30-40MPH in heavy traffic in the rain could very well end in pain. Doing 70MPH downhill on a deserted and relatively straight road in the mountains is fine. Kind of like what causes most accidents is inappropriate riding (or driving) rather that speeding on its own!
