We don’t often associate teenagers with driving Mercedes-Benz cars, unless they are some poor little trust-fund kids. But that hasn’t stopped the company from setting up something truly useful: a driving school for young people. Working on the entirely correct premise that the skills required to obtain a license do not prepare a new driver for the chaos out there on the roads, that 90 percent of car accidents can be attributed to human error, and that teens are more likely to crash than any other age group, the M-B school takes its pupils through class work, on-the-road training and supervised practice. There is already one such school in the United Kingdom, where the first-time pass rate is almost twice the national average. The Stateside Mercedes-Benz Driving Academy opens later this year, probably in or around New York. And teens won’t need to be Benz owners to take part.
