dumb that idea of remembering how many round to turn on your
wheel. prior to right turn, ensure there's no pedestrian nor
incoming vehicle. what's most important about executing it is, Keep
To Your Own Lane. which means, no wide turning, no sharp
turning.
you use engine brake when you need to slow down. for example, red
light in the distance, reaching a junction where you need to make a
turn etc. you do that by dropping to a suitable lower gear, and
leave all pedals untouched. of course, brake when you need
it.
