No they have tried it. It was a disaster, maybe bcus it was in the beginning of the server but overall it was a real disaster. The cars arent fast at all, but they make so close racing possible which means you need to have racing skills.
During those times it was obvious that the majority of racers coming from race 1 didnt had yet those racing skills . Which ended it up in crashing, pile ups and a lot of frustated racers. So there was a vote and a lot of LFS racers voted for bronze and above.
It took down the popularity off the server but there was a lot less crashing, wrecking and other sorts of crap. If you wanna drive get your bronze license. It isnt that hard to get bronze. The big step is Silver, once your there you have acces to more servers with more skilled drivers. It is a whole new world from silver. But you should get bronze very quick. If not well, sorry to say you dont have the skills yet to drive the UFBR then .
That's the point.. the UF Baby R isn't fast, but that doesnt mean you don't need any skills to race with it.
A monkey might be able to keep this thingie on the track, but it needs knowledge of racingrules and common sense (which some seem to lack) to have a fair and 'good' race..
Especially because races with the UF Baby R are that close, correct behaviour gets really important.
