Report Incredibly smart or totally dumb? in General Chat Posted March 11, 2020 On 09/03/2020 at 18:43, andydclements said: On the Aston Expressway in Birmingham (England's second largest city) there are lanes that are so smart that traffic in one direction uses at some times, and traffic in the other uses it at other, so there's no central reservation. https://en.wikipedia.org/wiki/A38(M)_motorway At least the use of hard shoulders is c70mph meeting stationery, rather than c140mph closing speed. Both are DUMB to the extreme Closing speed should be 120 as according to my recent speed awareness course no central barrier means single carageway not duel. Like thats going to make a differance!!!
