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.

Nice idea but it quickly runs up against budget realities.

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.

You need more than paint to build physically separated, elevated bus lanes.

Elevated bus lines are car infrastructure. You need enforcement and paint. And maybe a few concrete liners.

If you are elevating, don't use a bus.

Budget "realities" that somehow don't affect Mexico, only the USA?
