I manage a fleet, and it seems like I'm at a testing station for one of our vehicles at least every few weeks.
Before, that meant going on their hours in the middle of the day, waiting in line, etc. Figure 30 minutes minimum, at least 20 times a year.
Now? Show up whenever I want, 24/7. Almost no waiting (none at night, so far) plug in, test, pay, done. 5 minutes.
Whoever thought this up is a hero.
