I don’t think the original poster is having an issue driving a manual transmission, and advising that person to “improve his/her technique” is like telling someone to improve their technique in riding a bicycle. Once you get the hang of it, you’re done. I think the OP had to stop quick, on a dime, and stalled out the car. I did that to my own car once to avoid hitting a deer (from 50 mph-to-0 in a split second). I was lucky there was no one behind me.
Automakers should report the 60-to-0 mph distance/time instead of the opposite when trying to sell cars. Stopping quick is far more important and can be life saving.
