I want to buy a car recently. I heard that there are two kinds of throttles: electronic throttles and mechanical throttles. What are the characteristics of these two kinds of throttles?

The electronic throttle has no throttle line, and the motor of the throttle is directly controlled by the computer, which is slow in response, sluggish in throttle and fuel-saving.

The mechanical throttle has a pull wire to directly control the throttle, which has direct response and convenient control. The disadvantage is that when driving skills are poor or driving habits are bad, it consumes more fuel.
