When I was in Mexico City I was blown away and inspired that their bus lanes were actually physically separate from car traffic, sometimes they were even elevated a foot or so alongside car traffic. It made the buses so much faster! I wish bus and bike lanes in the USA were equally separated from car traffic. Different color paint and intermittent bollards don't cut it.
If something is worth doing, it's worth doing right and physically separate bus lanes is doing it right.
Bus lanes are usually not a budget problem. The problem is car centric laws and regulations that make it hard to impossible to take space away from cars.
Nonsense. The infrastructure in much of the US is already there. All you need is willingness to enforce it. All you need maybe is a bit of paint. Police could actually make some money.
