Вряд ли это все еще актуально, но вдруг кому-нибудь пригодится)
Drive is used with vehicles of four or more wheels.
You drive a car, a taxi, a bus, a lorry, a train.
Ride is used with vehicles of two wheels, or with anything that we straddle.
You ride a bike, a bicycle, a motorbike, a pony, a horse, a camel.
It is also used with vehicles that you are not driving.
Notice the difference:
If you drive a train, you are the driver.
If you ride a train, you are a passenger.
