>As for handling, the worst situation is that I'm going to need to swerve. Generally, all cars are capable of doing that.
Not true, I'm afraid. If your car has a big heavy diesel engine in the front and is front wheel drive with skinny tyres, you are more likely to continue in the direction that you were going in before you moved the steering wheel than if you are in a light car with four-wheel drive, active differentials, and the ability to brake wheels individually or send power to where it's needed. Of course, for the keen driver this means being able to corner well, but it also means being able to maintain control in a tricky situation.
>safety is about keeping a good distance and not speeding.
This depends on how you define speeding. If you mean not going so quickly that you are potentially unable to stop then you're right. If you mean staying below the posted speed limit then you're not. In many situations, a safe speed is well below the posted limit, and is dependent on weather, traffic, road condition etc. In many other cases a speed above the limit would be safe, but there needs to be a defined limit and it wouldn't be sensible to change it on every bend.
Safety is actually about being constantly aware of your surroundings and driving with the limit of the conditions, your car, and your own abilities, and being capable of preventing an accident in unexpected situations.
>Fast cars tempt people into speeding.
Every car on sale today is capable of exceeding the national speed limit. "Fast" cars may be able to get you to the speed limit more quickly but in the right hands a fast car is perfectly safe. When I was younger I drove crap old cars, and certainly when I was in my teens I often drove like a dick, in cars that struggled to get to 60. Now I'm old, sensible and earn my own money I buy cars which are capable and have a decent amount of power. In over 20 years of driving I've never claimed from my insurance and never had a speeding ticket.
