I'm okay driving a diesel car but not when refilling it at the station. It's not only the floor that is tainted with strong diesel smell due to the lorry or truck drivers in a hurry(usually less careful or considerate than common passenger vehicles), but the handle of the pump as well. It's usually oily when you touch it. Fortunately, we have a driver on our trips with diesel-powered cars.

On a bad day, especially on the North South highway, yes. At one point of time there are 3 to 4 large trucks or tankers queuing up with our (small) SUV, everyone fighting for the station. And usually the large trucks will take quite some time to fill up, so yeah, there is some tension build-up when many vehicles are "Fighting" for one or two diesel pump stations.
