High Streets for All

sat nav, google maps etc has transformed how people drive - it's now routine for all vehicles, from HGVs to personal cars to try and shave minutes of their journeys by take short-cuts down residential streets that were not designed to take that volume of traffic. Overrides/agreements should be put in place so that commercial vehicles stick to the major route unless their journey requires them to.
