An SDR can be made to jam, even if that is not the normal purpose. Just like a kitchen knife can be used to murder people, instead of its normal culinary purpose.
Of course an F0 can’t clone a rolling code as-is. I never said it could. But it can harvest and replay a single or multiple consecutive codes just fine, providing the original key is not used in the meantime. Only need physical access to the key while it is out of range of the vehicle.
This alone puts the F0 on dangerous ground as an “electronic device (such as a signal jammer) for use in theft of a vehicle or theft of anything in a vehicle”
People have locked out their original keys by messing with this before.
The point is that our laws are reactionary, vague, and open to too much interpretation.
If someone gets shit stolen out their car and I happen to be nearby, then I will become suspect merely through possession. Even without intent.
To add to this, I used to work at a physical security company, and we needed to alert the guards of someone attempted to jam signals. How do you properly test that? By jamming signals!
I guess this scenario could be resolved through licensing, but that’s a ridiculous solution since criminals could still get it.
It should be illegal to use a jammer maliciously or negligently. It shouldn’t be illegal to posses one. Car manufacturers should also be held liable for losses due to lack of protection against jamming.

Exactly!
