I don't think its currently even in corporations budget ranges.

Not sure how much resolution military sat's have (I assume you are USA), but even with them it might be challenging to identify teslas from top down.

And don't forget about clouds.

If you need such good resolution, getting some survey planes, or maybe some drones, might be a lot more feasible.

And you could then take pictures at an angle, which would serve to easier identify teslas.

Note that modern reconnaissance satellites can take pictures quite far off-axis (as demonstrated by the Morison leaks to Jane's).
