Daihatsu Kopen concept stars at the Tokyo Motor Show 2013

Rearview cameras may become mandatory

Rearview cameras may become a mandatory feature in all passenger cars by 2014 if US Congress approves a rule submitted by the National Highway Traffic Safety Administration. Auto safety regulators have taken the decision to submit a final rule to Congress after figures emerged from non-profit group KidsandCars.org that stated that two children die and about 50 are injured every week when someone accidentally backs over them in a vehicle. In one quite shocking public-service announcement KidsAndCars.org showed that 62 children could fit behind a large SUV without being visible to the driver in any of the mirrors.

McLaren’s Jenson Button & Lewis Hamilton get animated

McLaren has teamed up with Framestore to produce a series of animated – and amusing – cartoons showing on Sky F1. Somehow, despite having the British Grand Prix in one window and the Andy Murray match at Wimbledon in another on Sunday, we managed to miss this cartoon featuring McLaren, Lewis Hamilton and Jenson Button on Sky F1. It seems Sky F1 will be featuring a new cartoon from McLaren at every Grand Prix for the rest of the season, and if they are up to this standard they’ll be well worth looking forward to.
