For the last 14 or 15 years or more, I've always had one of each.
My wife had a manual when we got married, and I had an automatic.
Then, we both had automatics for a few years after selling her car (and getting her a new one).
Then, I got a truck with a manual, and she had an automatic.
Then, in 2006 she got a car with a manual, and we still had the truck with a manual.
Then, we sold the truck in 2007, and got a newer truck with an automatic. So, we had the car with a manual and the newer truck with a manual.
Then, last week we sold that truck, and got a new car with an automatic. So, we've got two cars now. One manual, one automatic.
So, I guess you could say both. I don't mind the manual. And, I don't mind the automatic.
But, I'll tell you what messes with you... Getting into the car (or previously the truck) with the automatic and trying to find that missing clutch pedal.
I've tried to hit the clutch more than a few times in vehicles that don't have one.
Something else that's fun is having a fast locking competition clutch in a truck with too much power and driving it on roads with glazed ice and standing water. You don't gain traction until you hit at least 3rd gear (and no I don't drive with studs in the tires - haven't since my first year of driving many years ago).
As for the missing clutch, we'll see what fun I have in the new car. It's automatic stick is on the floor. So, we'll see if I try and clutch and shift that
As long as I don't try and shift without the clutch (which you can quite easily do with most manual transmissions if you shift at the right engine speeds). Doing that with an automatic might result in a rather abrupt PARK
if a driver's struggling to exceed 100,000 miles on a clutch, I recommend they take a refresher course... or buy an automatic.
My mother-in-law went through a few automatics on her way to 100,000 miles. So, perhaps some people just shouldn't drive
The problem is that many people still don't understand that you should stop a car before moving from reverse to drive.
And, then there's the ones who think you should just leave it in 4-wheel drive anytime you have something other than dry pavement. So, naturally they kill their tranny's a bit quicker.
I think my mother-in-law fell into both camps there.
