I moved to the US 23 years ago and am saddened to see the direction driving in the UK has taken--and we seem to be slowly moving in the same direction here. At present, in Massachusetts speed limits are very low, poorly signposted, change often, and are lightly enforced. Our 4 lane highways have limits of 55 or 65 mph but most traffic cruises at about 80 and some cars go much faster. Entering a neighboring town in open countryside the limit is 30 mph, but entering the built up area it is 40. Go figure. Many towns round here now have a 25 mph limit unless otherwise posted
On a related issue, in the early 1900s Rolls Royce produced a model physically incapable of breaking the 30 mph speed limit, it was called the Legalimit and it didn't sell.
