Shouldn't you be paying complete attention to the road...
I don't agree with that, the majority of people who have driven manuals for a while can agree to this easily.
Why do I?
1) I was given the car as hand me down and I'm not really in a situation to be spending money on new cars, no complaints at all with what I'm being given, especially since insurance comes to around $50/month for comprehensive when factoring in that I'm only 19.
2) I enjoy it more, I've test driven dozens of cars and other than one exception, I'd say I always prefer the manual versions of the cars.
3) A lot of times the automatic will be a 4 speed, while manual would be a 5 speed... better gearing. Even if you don't see any advantage in gas mileage or daily driving, I prefer shorter gears for driving in and around the city.
4) I like it, I get bored in an automatic and while I can switch well between them, I occasionally find myself slamming the dead pedal in hopes of a clutch.
If I were to ever fall asleep in either car, it would be an automatic.
I am not saying anything about gas mileage, reliability, etc. in comparison between the two. The simple fact is that I like it because of one or two reasons and I am naturally much more attentive in a manual transmission.
