Of course basically not for everyday driving.....ha! ha!
Ai yah what you all talking heel and toe not for everyday driving and slow speed driving. I use it all the time. Saves on clutch and syncros. My manual civic has done 250K km and still on the 1st clutch and 14yrs already.
There are basically 4 methods that all good drivers of manual cars have to learn. Its so hard to describe in words how all four works, it has to be shown to you and you have to go practice. My 4 basic methods are:
1. Heel and Toe
1. Full throttle quick flat upshift.
2. Full throttle-closed throttle quick upshift.
3. Clutchless shift.
5. Smooth upshift with out slipping clutch.
6. Left foot braking only used for racing or two quick short pumps on the brakes to seat the pads before braking.
