A Buddhist priest once taught me a very simple and effective exercise to combat that sort of thinking.
As you drive, imagine your car in a bubble. Then expand your bubble to include the vehicle in front of you.
It started with imagining a bubble around yourself (not in a car necessarily) and then expanding it to include the person nearest you.
It's more impactful than it sounds. You quickly come to see/feel them as part of the "you" team.
