I love driving my 34 year old car. It only goes 140km/h max and that is fine for it. I consider it a fun car as well even though it has the reputation of being a shopping trolley for old people. I can’t see where you would would draw the line of fun car and what that would do for road safety. Most crashes tend to happen at intersections because of inattentive drivers or confusing situations. This behavior is promoted by a sense of perceived safety which people get from a “self driving” car. If I could snap my fingers and apply a ban on a car type it would be suv’s without a doubt. Big cars in general also give that sense of safety which is somewhat true for the people in it but they kill more people involved in crashes with them. Now for your last point about Top Gear. Quite a strong opinion which I do not agree with. They tend to close roads to do their scenes. If you ever go to one of those beautiful roads you will find out that they are very popular and the speed limit cannot even be met. In conclusion, make cars small again.
