You're comparing unexpected bottlenecks to permanent lane reductions on under-utilized roads. It's a bad comparison for a few reasons:
- Bottlenecking creates traffic. A two lane road that goes down to one could have traffic where a one lane road wouldn't because of the merging required and traffic waves caused by braking.
- Traffic patterns adapt to permanent changes.
