A Something More Serious Question about vehicles.

soz i had to lol.
Being the noob that i am and always will be. Is it possible or planned to have cars differ in speed in anyway shape or form?
I know there are mods for this. BUT i am a noob lol i am asking if there is a way to make it easier for server owners to increase speed of cars beyond what is possible atm.
I know there is concerns of lag and falling through the world or the jitter bugs as i have seen this in the past.
However, If you have the right hardware, Network speed and player side is also good enough to match the host,
you can get some pretty insane speed going with out issues.
Will it be possible to have cars adjustable server side knowing the risk of possible issues?
I mean i wanna go from driving miss daisy to Fast and Furious off a mountain just to see how far i can jump before i die, packing 3 other screaming players along with me as i drive us to our deaths.
I just wanna be able to edit this like i do for weapon damage in xmls.
I dream of one day again having a race for my gaming group.
Something like we did back in alpha 13. but to have real speed and skill needed to win.
