Yes, but:

1. In countries where that is popular, due to unfortunate events, they are not allowed in many indoor parking lots.

2. Does anyone have a comparison of pressures and volumes between a car's propane tank, and the Roadster's COPV?

3. The converted car propane tank does not have exhaust ports in various directions that could shred meat, whenever the driver chooses.

For 2: my basic research shows that Roadster's COPV has 50x to 100x the pressure.
