About the car going uphill.

Turn it off before the ramp, or you will slip away once it starts and stops. Remember to turn off the engine before crossing the deep wading road, and it is best to turn off the engine before reversing, otherwise it will be very annoying. I usually drive, but now it's cold and he doesn't work. The long bus is only useful when it is heated. If he starts and stops, at least it means that the car is in normal condition.
