I've never seen an urban center where "free and cheap parking is widely available", or one with a speed limit above 25.
Another factor is that urban speed limits vary widely in how much they are actually limits. Research is clear on the fact that road design has at least as strong an influence on driver behavior as posted limits do. Without rigorous enforcement & given the wide streets common in these places, driver behavior tends towards interpreting the limit as the minimum speed they are entitled to, rather than the maximum to be attained only when safe.
And finally neither I nor anyone else here know what you've seen so that's a very silly limit to place on the conversation.
But that’s exactly what it means. It’s not available to people. Someone else already parked there.
Have you tried to park on the street in NYC?
Parking is most certainly not widely available. If spots exist but all of them are always taken, that means zero availability.
If you go to a restaurant with 100 tables, all of them full and a 2 hour waiting list, would you tell a friend on the phone "Yes they have lots of tables available"?
