Can small people move big things?

Whilst I was waiting for the bus today I noticed a 4WD with hazard lights on like the one seen below. Knowing that the bus was going to arrive at 12:58 and now being 12:56 I only had to wait a few minutes before my bus would arrive. Then to top it all off the driver of that car, he asked me to help move his car into the driveway which just happened to be on a hill. I dont know what was going through that driver's mind but a small kid like me how was i going to be able to push a 4WD up the driveway.

Luckily another man came to help out. Only to result in me watching my bus go by. So after we managed to move the car i had to wait another 20 minutes.
