Driving various of our family's cars at different times, I have been amazed at the attitude of other drivers changing according to the car I drive. In one of my kids' cars (a FIAT Panda or a Skoda Fabia) I have noticed how aggressive and intimidating other drivers can be to smaller car drivers. That changes in my car (a Mercedes E320 CDI estate) when drivers don't tend to "try it on" and seem to treat the car with more respect. However, the biggest difference is when I'm driving my pride and joy, my Morgan Plus 4. In the Morgan, I am the recipient of smiles and waves (predominantly from grandfathers and small children) and invariably I'm let out at junctions. I imagine it is a throwback to how are roads were in a less rushed and congested time.
