Great article here on Mercedes Level 3 and 4 Autonomous driving capability if you're interested.....there's a little dig in here at Tesla too, PLUS INTERESTING TO NOTE THAT AUDI, BMW, INTEL and BOSCH are all stakeholders together in the HD live mapping co ...........

Within a couple of minutes, the lights on the buttons and the steering column flashed red, indicating the car was handing control back to me. Although the snow had stopped, the fast-fading daylight had fallen below Drive Pilot's operating threshold. "As you can see, the use case is edgy," acknowledged Gregor Kugelmann, senior development manager for Drive Pilot. "If it's too dark, too wet, too cold, or there's too much snow, the system will not operate."

Now, before the Elon bros start sniggering and going all in on $TSLA, it should be pointed out that Drive Pilot's limitations are not due to the technology it employs but have been artificially imposed out of an abundance of caution on the part of both Mercedes-Benz engineers and the German government. Drive Pilot, which will be available on German-market S-Class models within the next few months, will only allow Level 3 autonomous operation on certain sections of the German autobahn network at speeds up to 37 mph, and only if certain weather conditions are met.

Though they won't comment on the record, the rolled eyes, half smiles, and shaking heads tell you exactly what the engineers in Stuttgart think of Tesla's so-called Full Self-Driving (FSD) system. Privately, they're astounded FSD Beta testing is even allowed on public roads. Getting Drive Pilot to meet Mercedes-Benz's own engineering and safety standards—not to mention those of the German authorities—has taken years of work in test labs and on the proving ground.

The Drive Pilot development program has so far racked up more than eight million test miles—"We drove every foot of the entire autobahn network at least twice," says Kugelmann—and the current test fleet comprises 260 vehicles. In 2015 Mercedes spent almost $1 billion acquiring a stake in the HD live-mapping company Here from Nokia to provide highly accurate baseline data for the system. (BMW, Audi, Intel, and Bosch are also stakeholders.)
