No you are not alone, but it's not a rational position, nor one that could possibly be supported by any evidence. I drive three different makes of car, not including when I use hire cars which will be different again. I don't notice any difference in the way other drivers react to my driving. Probably because I'm the same driver, driving in much the same style. In other words, the driver is typically the critical variant, not the car.
This ^^^^^ I regularly drive 4 different types of car.. Honda Civic, BMW X5, Merc SL and Audi TT. I see absolutely zero difference to how I am treated on the road in any of them... I do think the whole 'typical INSERT MANUFACTURER NAME HERE driver' is a myth... twats drive all different types of cars and some even ride bikes or walk on the pavements.
