Interesting read. I've observed the following over many years of the Zed:
You really do get tailgaters. I think it's because the Zed is low they see the next car ahead and thus drive to that one's speed and brake lights, not mine
Few clowns at traffic lights, but get just the same in the Jag. (difference is the Jag surprises them if I do choose to rarely floor it)
2 types of folks on the road - those that like sports cars and let you out, allow you to pass, move in on motorways and the others that hell will freeze over before you pass, exit the junction, etc. Seems to polarise opinions.
Realistically though very few issues, unlike from some mates who drive serious Italian exotic metal and live a life of hell on roads with kn*b head drivers, keying, spitting and next minute acclaim, photographs of the car, etc..
