Vinyl wraps - can be cut to arbitrary sizes - can be stretched a bit to make them fit non-flat, non-cylindrical surfaces I doubt either of these can be done with this without breaking the solar cells and/or the sheets. Specialized shapes for each car type probably could be made, but those, not being flat or rollable, wouldn’t be easily distributable.
