Volvo cars will be able to tell if you're driving tired

Volvo is currently testing in-car sensors that can monitor driver alertness -- ones that can determine if the driver is becoming tired and inattentive.

Porsche makes £14k on every car it sells, Bentley makes £12.7k

Porsche made £14k on every car sold in 2013 If you need an illustration of how much more profitable high-end sports and luxury cars are than mainstream cars, VW Groups sales figures demonstrate it perfectly. At the extreme ends of the profit per car spectrum, Porsche made an enviable £13,931 for every car it sold in 2013 and VW made just £615 (although SEAT actually lost £330 on every car it sold) .
