Rover-It's not hard at all to switch from haul truck to car since they both operate basically the same way. Accelerator, brakes and gear selector are all in the same position and work the same way. If I'm really tired I may try to move my car's gear forward to go into reverse from park since it is that way in the truck or I may reach for my ******er on the steering column in to slow down, but that's pretty rare since my car's cab feels completely different than the cab of a haul truck.
It's freakier switching from equipment operating to driving either a regular vehicle or a haul truck. A Cat Haul truck cab is damned near exactly the same as the cab of a Cat Scraper.
The first time I went sliding in winter in my haul truck I instinctively reached over to drop my can(the back portion of the scraper) to stop and shoved my lunch bag into the door since there were no implement controls there.
Worse than that was when I left Casper for Rock Springs after I had been training on a dozer for two days. With dozers you set your throttle speed with a hand lever and use your right foot to slow down(DEcelerator) rather than as an ACcelerator. So anyways, after training I was cruising down I-80 at about 85 miles/hour and went to pass a semi. He decided to pass the guy in front of him at the same time doing about 60 mph. I hit the gas to slow down out of habit and jumped to 95 mph. Fortunately, on the dozer the brake is at your left foot which is the clutch in a standard trans car and I hit that at the same time disengaging my trannie or that semi would have had a Subaru pancake on the back of his box.
