The ideal amount of fraud is greater than zero.

Putting a bunch of technical compliance controls in place to stop the one-percent of bad actors is going to increase friction for everyone else.

They will probably re-evaluate after this. Another thing is to send additional security with a trailing car. Hopefully assigned at random so it can't be someone connected with the driver. I know someone was shipping shelled walnuts and they did that as a semi full of those things can be in the many hundreds of thousands of dollars/euros in value.
