I have no problem with powerbuilds as long as they pay a price for having some stats ridculously low. Alts are abused to remove consequences of low stats. Very often it's open cheating with dual logs. All this sugestion would do, would be faster travel than now for everyone who has to travel alone, for more balanced characters and for smaller groups of people and making cars even more useful for large groups of people with low outdoorsman which are usually led by a lame one-purpose alt.
As I said, you need to think up anything that'd be charisma worth, except for being able to make teams (of NPCs), because many people wouldn't play a game with tons of NPCs, there are no real consequences of dropping charisma low.
Other stats are already being somewhat balanced, such as low luck resulting in more bad things happening for character (being easier to blind, critical failures...), while low charisma results only in merchants sending you away.
Self-purpose taxi alts are useful only for cheaters, because they wouldn't be able to transport themselfs, but only the teammates, resulting in one man missing the show, instead I see more people (atleast from my surroundings) using taxis capable of doing combat or leading more NPCs. And because of their encounter avoidance being already high enough, there's little reason to raise the skill above 200, so I don't see much problems with 300 OD alts.
Also take note that cars make outdoorsman completly useless which is not that good thing as well.
So better solution would be to make cars affected by OD some way ( be it probably less damage taken over time ), cars more useful without alting (tentalt#242 reporting), charisma completly revmaped and characters of one person being linked some way.
You see I disagree with you about Alts 'Not being a major problem' plenty of people in game have turned around to me and said "You need more alts - Buyer/Seller, Fighter and Crafter Alt''
Your crafter can be Buyer and Seller in fact, because it's only matter of having 3 charisma. But then again you can have your Fighter crafting already, as well as trading, because when stats distributed right, you're still able to fix stuff at expense of First Aid and maybe Doctor (unless you're crafting drugs ofcourse), while still having big enough stats for fighting. And to be honest, it's possible to play and not requiring to trade or craft at all, and it's not only encounter farming, but more important part of MMO game, often forgotten, having some friends doing this sort of stuff.
