High pressure is not so bad as long as it isn't too high.
Not sure that a moderately high pressure is any worse than even the softest wash cloth and the best soap. Even with the best wash stuff, you will still scratch your car every time you wash it.
I have switched to using a moderate strength pressure washer at home, and have been much happier with the results than putting a wash cloth onto my car. I first do a low pressure rinse, then a medium pressure rinse, then a low pressure detergent application, then a high pressure rinse. I then spray with quick detailer and dry with a microfiber towel.
With this method, I am never moving dirt around on the surface of my car. Mind you, however, my home pressure washer is obviously nowhere near the pressure levels of commercail applications.

Re: High pressure is not so bad as long as it isn't too high.
it's best not to use a mit...of any kind. dirt and debri gets caught in those and scratches the paint. use a clean sponge that you can fully rinse out each time after the wash.
as far as touchless car washes, they don't get the car clean...even less so than the brush washes.
washing with only a spray, you are not removing all the dirt from the surface. then when you finally wipe dry with towel, the dirt that was not lifted off the surface is still there and being spread around as you wipe. so you ARE moving residual dirt along the surface. the fact that the car is still wet is minimizing any scratching. but, i would never do it this way.

A waterjet is only 30x higher pressure and cuts through steel like butter.
I use a Griot's Garage boar's hair brush with a gentle car wash soap and lots of water from the hose. The wash pail is from Griot's Garage and has a ledge so that the brush doesn't get down to the bottom where the dirt might settle.
For the wheels, a seperate wash bucket with four brushes, including another boar's hair brush for the painted wheel surfaces.
Bi-annual Zaino sessions helps all of this work and keeps the scratching at bay.

while we're on the subject
the method i use is:
-sponge, bucket, hose end sprayer
-wash in shade
-rinse entire car before washing
-use liquid soap along with carnuba based wash/wax
-wash section and rinse, repeat for entire car
-switch out bucket for new soap and carnuba wash/wax add
-wash wheel wells, rocker panel, wheels with different sponge
-rinse wheels/wheel wells AND rinse entire car again to get off any debri that may have been kicked up from doing wheel area.
-wipe dry with microfiber towels, dab wheels dry
-wipe down door jams and kick plates while still wet
-do interior cleaning and detailing.
for what it's worth...

Since I keep my cars 10+ years - and I'm a old mfer - I've never had a finish marked by either
a pressure washer or my method of washing the car at home - using Ivory liquid dish soap.

i'll bet it keeps your hands lovely too
the ivory liquid : )
anyway, are you regularly adding some kind of wax on top of the wash with ivory liquid?
this is why i use the wash/wax products with liquid carnuba(Kit, Raindance, etc)...to offer a protective wax coating between hand waxing...which i try and do is little as possible.
