How many years of free public transport would $22B buy?
I recall the 50% price cut during COVID (for the whole country) cost the government a few hundred million for a year. This was during COVID so it didn't get higher uptake, but let's assume there was a higher uptake and make it $500M for 50% off per year, or 1B for free public transport per year.
We could have free public transport for everyone for 22 years for the price of this one road.
