Predicated on humans lazy gene that keeps every urban centre in UK gridlocked every day at happy hours>

Actually adressing gridlock is relatively easy: price it out. It is currently quite easy to monitor intersections using smart image capture/sensoring and ticket anyone-- willing or not-- caught in the gridlock-- see, for example, the California Anti-Gridlock Act of 1987. Yellow grids or warning signs are clearly insufficient. Conventional ticketing takes too long-- an average of 10 min. and an increase in congestion--- and does not have a big enough a net. Increasing the chances of being penalized as well as the price of gridlock for those involved (cost of the citation which in California is currently around $300 but also indirectly via insurrance premiums) vs the increased speed of traffic from their reduction might not wholly end gridlock but significantly reduce it.. and perhaps also train motorists some manners. The problem right now is that in many countries getting into a gridlock is not punishable-- in Germany, for example, even blocking an ambulance or emergency vehicle results in, at most, in a fine less than that of riding a bicycle without working lights (by daylight)-- or hardly enforced (and when citations are issues they are relatively low).
