Umm, no. I tried their Drive Pilot L3 system in Germany over the Christmas holidays (MB EQS) and of 8 hours driving, it was only available for me to drive for 12 minutes (and not a continuous 12 minutes, either). Granted this does not mean the system is poor quality, but it's horribly impractical... if it's rarely to ever available.
It sounds like they are more responsible than the other companies.
Exactly. Using your customers as guinea pig data collectors for an undeveloped system seems to be the go-to. There have been noted fatalities due to this.
