That's another thing I don't get, being limited to a 125 for a whole year.
You're right about the car, nobody stops you getting a more powerful car right away.
I went from my first car, a 1.3l Astra to a v8 in 3months (after obtaining a license).
Nope, didn't have to drive something with a low engine capacity for a year.
I'd say cars are more dangerous as well in an accident, In most cases I'd prefer a motorcycle would hit me than any other vehicle if forced to choose. Unless they come through the window, eek!
Still, it's not like you can't hit 70/80 or more in your 300quid banger.
I know I can if I wanted to.
They could say that you should get used to a smaller bike first, learn to handle it.
Yet they don't mind me going from a FWD 60 odd horsepower car to a RWD 270hp car

I wish someone would do something about the motorcycle thing, it's ridiculous.
They talk about safety but don't tell you if you get things wrong in a test, should be illegal.
Bunch of muppets running things, by no means do I consider myself to be that smart but all it takes is an iota of logic to fix these things!!
Money > *?
I thought I should disclaim that by no means am I saying the people who work there are muppets, it's the decision makers and bigwigs up there I'm angry with. The employees just have to enforce the rules in their job role of course.
Although I had problems registering by car because it's a classic American and they said I needed some proof trail of ownership which I did have but apparently not enough info.
I had to make calls/emails to people, previous owners of the car, workshops, vehicle standards in America, visit websites, provide proof of how transfer are made internationally before they considered registering my car.
That's right, they wouldn't, until I did their job for them to prove It should be registered.
They also tried to charge me a £250-300 ish inspection fee when it should have only been ...well it's been months now, £70 I think.
I learned in the past year you get nowhere unless you push push push and argue yourself blue and purple.
