[SystemSafety] Mercedes and Autonomous Driving

[David Crocker]

There are several production cars available with ALKS. Tesla has had it 
for a few years. My Ioniq 5 has it, along with automatic lane changing 
if I command it using the indicators. It claims to be Level 2 autonomy. 
AFAIK it has no maximum speed, but it complains if I don't keep my hands 
on the steering wheel. So I guess the certification is indeed all abut 
whether you are allowed to take your hands off the wheel.
