Very nice video Bensla, the quality is very high and you have great way of presenting! And hey, this seems like a nice, effective and fun wash routine, that you made your own! The Tesla is looking mint, and washing it this way will surely keep the marring to a minimal; keeps it looking nice for a long time. Half an hour is a nice amount of time to spend on washing your car if you like to, not too fast, not too slow. Good to hear that ONR makes drying a lot easier. I must admit I went straight from the self service brush and not drying the car, to ONR, the BRS and MF towels, so can't compare it to anything!
It seems however, that you are intrigued to shave some time of off your wash routine, so allow me to shine my light on that!
Yvan Lacroix is the master of car-cleaning/detailing efficiency, if you don't know who he is, look him up on YouTube! He suggests to let ONR dry on the surface for about 80%, after a wash, and then dry it with a waffle weave or twist loop towel.
I've found the above to indeed be the fastest way to wash a car, my current record sits at 7 minutes (excluding wheels and drying aid) where I firstly wash the whole car and then dry it completely. No smears, even on windows, but some water dripping from cracks. Interesting is the washing of the car, applying ONR everywhere with the BRS, takes 3 minutes (small 90's Civic). I did find a video of Chemical Guys (I don't like their company, but okay) in which they state one can dry a car in 1 minute. Sadly, they don't show how to. It doesn't seem to be the safest wash (Duuhhhh?), as on my completely corrected roof, I noticed some swirling appear over time. Nothing a quickie polish couldn't take care of though, and that was after a couple dozen washes.
I do have some trouble with my drying towel (TRC Double Twistress) being grabby on the paint, which I'm trying to figure out. It seems to be whenever there is any kind of moisture on the paint. If it could glide smoother it would save lots of time and effort. Maybe I need to use a drying aid? But which one; Optimum Car Wax doesn't really seem to help. Optimum instant detailer?
