London's GPS-based speed-limit trial puts Big Brother's foot on the gas pedal

A fleet of 12 Toyota Priuses in London have been fitted with GPS-linked speed limiters to measure how drivers respond to having their speed controlled by a computer rather than their own feet. For now, the trial is local to London, run by Transport for London, the agency that manages the city's roads, buses, subways and trains. The agency is using its own fleet of Priuses for the test and will add a bus and a taxi later this year.

New Mercedes S 65 AMG revealed as S-Class range-topper

But for now, the newly-revealed S65 AMG is indeed the top of the range in the new S-Class and will get its public debut at both the Los Angles and Tokyo Motor Shows later this month.

Jaguar are being a bit precious with the full details of the new XJR, but they’re calling the new XJR the ‘Dynamic Flagship‘ of the Jaguar range – which is promising when you consider how fluid and able the XJ already is.
