Very interesting like always in your videos. In Finland conveyors have slower speed. One difference is that we don't use so much foam and high pressure is always before the brushes. High pressure is meant to clean very dirty car before brushes so they stay clean. Also contouring dryer is typical and it's more complex adding cost to the system. In conveyor systems I always look how well wraparounds clean back of the vehicle. This seems to do well.
I've always been interested to the in bay automatic systems you use! A lot of the time they're stationed outside away from the fuel station or car wash. Do you know why that is?
