Increasing UF1 Income rates

[gyunter]

Suggestion:
Increasing UF1 maximum income rates up to +5
I may be wrong, but income rates on UF1 used to be higher back in 2008.
Description:
As I clearly understand, current car income rates depend on the vehicle class such as TBOs, GTRs etc. XFG, XRG and UF1 are in the same income group (+4), but it's not a really good comparison as UF1 is a way too slow. My suggestion is to place UF1 to it's own income group with a maximum value of +5.
Pros:
- Forcing people to drive slow vehicle may decrease an amount of accidents on the roads. Those who has a goal on making money will stick to an even slower vehicle such as UF1.
Cons:
- Increased money supply (due to emission). That's the serious problem even for a TC economy. Fortunately, TC has a set of mechanisms to withdraw money from circulation, e.g. money loss for speeding may be increased slightly for the balance or a price for a UF1 raised.
