> Speaking of toll booths vs electronic debit, when I lived in the Bay Area, I had to commute from east bay to west bay every day. For the first 4-5 months, I was paying cash, because in my scant spare time, I hadn't had time to get transponder and direct debit set up. I was paying $35/week. I didn't become less aware of that cost when I switched to the transponder, because the actual cost was time. Time is something I have very little of, so adding friction just wastes my most limited resource.
You just proved my point without even realizing it.
When you were forced to pay cash, they were forced to show you the price. You even remember the amount now, presumably years later. If they could have you pay cash without seeing the price I’m sure they would. If the price had changed from week to week, you’d immediately realize it because the amounts you’d interact with would change.
But that’s only possible with a purely digital system. As all the numbers happen behind the scenes.
Ask yourself this, why don’t any of those automated toll booths show the amount you “auto paid” rather than just “Ok!” Or “Paid!”? It’s because they explicitly do not want people to know what they are paying so they can raise the rates with minimal flak.
