The other day someone linked me to this report on a trial of Intelligent Speed Assistance on London buses. ISA uses GPS to obtain data on where you are and thus what speed limits apply, and then compares that with the speedometer, and either makes a nuisance of itself warning the driver that they're speeding, or (as in this case) actively limits the speed to the speed limit.

( transport geekery )

More than anything else this strongly suggests to me that what TfL (& the police?) really need to be doing is enforcing 20mph zones, on everyone.
