What two things can tell you when it is time to change gears?

Answer options

Why

Drivers judge shift points either by engine speed, watching the tachometer for the right rpm, or by road speed, knowing which mph range each gear covers. Traffic, following distance and weather affect how you drive, but they do not tell you when to shift.
