I think you’ve hit the point. At the end of the day it is based on a commercial vehicle, of which the vast majority are only used during daylight hours. Maybe we should be praising VW for offering alternative options and so saving commercial users a fair amount of money on a legal requirement.
I would expect a company that produces some of thee most expensive LGVs to make a slightly shinier light. Having a gripe with your van is going to happen. I’ve never truly been 100% happy with any vehicle but no issues have ever related to a safety aspect.
