And how often are those fighter pilots confronted by pedestrians stepping out in front of them, or a traffic light turning red, when they are flying in the air?
Having flown and with many hours riding in various planes, I can assure you that when flying, there are usually far less obstacles and distractions while cruising aloft. You can safely spend several(or more) seconds for a touch screen or other controls, unlike driving a ground vehicle.
Take-off and landing, as well as intricate manuevers/formations can be another kettle of fish, but these usuall take up a very small portion of most flights, even fighter jets.
And while they may have touchscreens, there is also a very good reason fighter jets almost universally have HOTAS(Hands On Throttle And Stick) systems in cockpit for actual combat when stress is high and attention is needed on surrounding conditions/threats/targets, and the touchscreens are mostly ignored.
 I have spent some hours(40-50?) only piloting a plane, and those hours were in Cessna 150's and 180's.
I have had the good fortune to be a rider in an F-4 Phantom(1974) piloted by my neighbor who was a US Marine fighter pilot with two combat tours in Vietnam(4 kills, 2 assists), and then again in 1989 I got to ride in an F-15C with an air combat vet(no specifcs where given). I observed very little touchscreen interaction, but a lot of attention paid to gauges and controls, once take off happened, it seemed maostle Mark 1 Eyeball looking around at the sourroundings and instruments, and interactions with HOTAS.
I pride myself as being an adrenaline junkie, and salivate at the prospect of riding the most outrageous rides available. I was Airborne in the US Army, and had over 1000 jumps(static line, HALO[my favorite!], HAHO) before an accident left me with Teflon kneecaps, and relearning to walk. My only regret is that I can't jump again.
But, none of that compares to those two fighter jet rides!
In the F-4, I think I creamed my jeans. I certainly fired up a Camel back on the ground, and with a grin the undertaker could not have taken off my face upon death...
With the F-15 ride, my little brother got some payback...sort of.
He was Chief Avionics Tech boss(I forget his actual rank and title, the US Air Force system never made sense to a ground pounder like me), and a Colonel was taking it up for a 'training flight'(he needed 'air hours' to maintain his flight status), and my brother told him that 'My brother bet me you could not scare him.'
Apparently that was 'a challenge issued' that the Col. felt duty bound to take up.
I certainly creamed my jeans, but I'm afraid I also pissed myself, and came close to soiling my drawers, all while clutching the 'barf bag' in a death grip. I did not have to use it, but it was REAL close several times.
And I would love to do it again.(I've also been a passenger in two Huey copters that had engine failure and autorotated down...no sweat)
