Strange place for the door in to the cab. The idea behind this was a safety matter for the driver. In Sweden at that time, we had just turned from left-traffic to right traffic. When we had left-traffic in Sweden, the steering wheel was at the left sid of the vehicle. Not like in the UK wiht a rightside steering wheel. Thats why the manufaturer had this front door, just for safety reasons. The driver did not have to step out of the cab into the street.
