100 miles between charging (on average for this experiment) is not great. Having trouble with that being more efficient than 150-200 miles between charges. Much prefer arriving at a hotel near empty and charging at night.
Good move adding the warning tag. A 30A to 50A receptacle adapter will work but is not to electrical code or UL approved in the US.
If your flawless charger never accidentally increases current, you will be safe. If not, pray for a blown circuit breaker instead of a building fire.
It is safer...
Does not bother me - it will make the Porsche team work a little smarter. And I would not consider the Dodge/NASCAR appearance of the Audi a positive attribute compared to the Taycan.
