So my friend has helped start this new startup and I thought it would be of interest to some readers here.
Basically the idea is that he has a whole bunch of branded Chevy sparks parked throughout LA. Every driver gets two free hours to drive car around (free as the advertisors pay for their "billboard" to be driven around). After that each car is only $6/hr (I think this is just to deter drivers from keeping car for extended periods of time).
More info
hereI am in direct contact with this friend so I can get any questions answered.
I think this can be great for the tourist just visiting LA. Its basically a free rental car (Albeit a spark
but hey free is free)
