Hmm. Caravans didn't use cars maybe because they couldn't afford enough cars to make it work, or there just weren't enough cars. Let's assume that the Fusion-cell powered cars of the Fallout universe are similar to our cars in that they are most efficient with their fuel when traveling about 60 MPH. Maybe you can't always make that speed, but even cross-country you can average probably 30 or even 40. But that assumes you have enough cars to make your run using entirely cars, which is unlikely. Throw in just one Brahmin cart, which probably can't move faster than 5 MPH, and the effiecieny of the cars is in the toilet pan. And all this assumes that that many suitable cars are around to be purchased, and that the Caravanners can gaurd them. You don't haul much in a Corvette or an MG; and you don't get to far too fast jacking a Brahmin cart, but all it takes is one lucky punk who found a Master Key in a locksmith's tools or can otherwise subvert a car's security system, and the Caravanners are out a $10,000+ investment plus whatever profit it made.
Your logic is flawed.
A car is about 8 times faster than moving by foot (IIRC). This means that it's really fast to get somewhere, and you need a lot fewer guards because of the speed of the car.
Then there's the fact that you can stow a shitload of stuff in the trunk, and you can also attach a cart. Suppose then that this is about a quarter of what a normal caravan carries.
Now, suppose an upgraded car is about $1,000 (about the price of the upgraded car the chop shop asks). The fuel price per four trips would be about $1200 I believe.
However, in the time a caravan can do one delivery, you can make eight, with hence a total of double the freight. At a much higher speed, this will probably fetch a higher price as well. You'll also only need a quarter of the guards. At about $800 per guard, and 3 guards, this makes $2400
Total start-up cost: $1000
Cost per four trips: $3600
Now, to run a normal caravan, you need to pay 12 guards, at $800 a pop. This makes for $9,600. And because you make (more than) double the money on a car caravan (in the same amount of time), the car caravan is a lot more profitable.
But John Bishop clearly wanted to buy a car; implying that a medium-level crime lord could afford to maintain one. The existance of the Chop Shop imlied that cars were, while not common, at least known.
Yes, as I said, the game was quite ambiguous about it.
MCA commented once about NCR's 'fleet of cars', which is a pretty retarded thing for a depressing post-apocalyptic setting. But, as I said, several people can't believe that cars exist. And yet there is a chop shop that can pay about 7 employees on fixing cars for 1000 or so per car. That'd imply there's quite a few cars around.
Besides, Bishop was a pretty high-level crime lord.
