Agreed. Engineers and accountants—on average cheapies.
Some engineering students and Carnegie Mellon figured out how to do it for about $80K as a class project. PennDOT ended up looking rather stupid when they did.
reminds me of when my thingamajig that controls the spare tire in the trunk somehow got stuck ...went to the dealership....$200 to fix.....drove to Discount Tire, they fixed it in 5”....for FREE.....
