You can actually smoke your tires once you get some practice in. I've always owned a manual and currently have a 6spd rwd so smoking tires is no problem.

If your gas pedal is close to your brake pedal you can actually roll your foot over the brake onto the gas. It takes practice (I learned it in racing classes but for a different reason). Just something to fuck with.

You don't really have to put your car in gear at a light but I always do cuz you never know what could happen. I see many people go to neutral in turns. If you have to accelerate for some reason you're fucked. So keep it in gear.

Learn to use your E-brake on hills. This way you won't roll backwards and hit somebody.
