I did it driving semi... Honestly the new cars and trucks today pretty much drive themselves, there isn't any skill involved anymore.
Shifting without the clutch is one of those things that takes some skill without screwing up your transmission, it's about learning and knowing your rig, being able to feel it and listen for what it needs to drive smooth.
Just thought I'd see who else was doing it.

It's all about RPM's and wheel speed....Just have to have them timed right in a gasser.
Big rigs have real heavy flywheels to slow engine speed down to allow you to shift quickly from gear to gear.

I drive truck for a living.......own my own semi.....and maintain it as well and if you know what you are doing, you can "float shift" smoother than you can with a clutch. Less strain on drivetrain components if done correctly. Done incorrectly......youre going to be tearing **** up!

I have done it in my truck. I do it all the time when I drive my Dad's car hauling rigs.
I even do it in my 6 spd TDI, usually in traffic. The TDI is incredibly easy to do it smoothly, despite the cable shifter (which I hate).

Lots of people do it but it puts strain on the transmission components. I used to be a manager for a large trucking company and we sat trough an Eaton presentation on why you should use the clutch. Even if you think you are making the "Perfect shift" there is strain on components where there shouldn't be any.

But on a serious note, that is why they developed synchro's, until pretty recently synchro's weren't durable enough for anything but the light duty market. It's a bit of a trade off, weaker gears for a drivetrain that will be happier longer.
