I don’t like that it creates separate classes of infrastructure for citizens based on their ability to pay. Even the non-toll highways had an HOT-like lane you paid per-use to drive on that was often significantly faster than the free lanes.
It makes a system where I suspect many people won’t want to pay to upgrade the free infrastructure because they don’t use it, and people who can’t afford the daily tolls waste even more time in traffic. The fast pass lane are even worse because they cannibalize lanes that could be used to alleviate general traffic (and were typically sparsely used).
The tolls were substantial for some people. $3-$8 a day on toll roads (ie no fast pass lane). At $8 a day, that’d be $40 a week, ~$160/month. That’s nearly 20% of the weekly pre-tax income of someone making Austin’s $22/hr minimum wage.
