Not sure about how good or bad it is in the US, but in the Netherlands (a place that is known for good infrastructure) it's definitely not perfect.

I never realised until we got a baby and I started walking with a stroler. Way too often the sidewalk is inaccessible because of cars or bicycles. Also lots of places without ramps or elevators.

Europe very sound protection for the disabled. Putside of historical buildings built before disability care you won't find better access anywhere.

But that's the point: Most buildings were built before disability care, and haven't been upgraded.* Think about your favorite restaurant, bar, kebab place, corner shop etc. – I don't think any of mine are wheelchair accessible. Also good luck taking a train in Germany, where many platforms aren't wheelchair accessible and they might or might not have a lift to get you into the train.

The Americans with Disabilites Act (ADA) is miles ahead of any legal framework that I'm aware of in Europe. The US is a broken country in many ways, but that doesn't mean that literally anything and everything has to be worse than in glorious Europe.

*The former is true for the US too, but the ADA still required many of them to make reasonable accomodations.

America has way more wheelchair ramps due to the critically obese population, so the statement is still mostly true.

I get that Europe is pretty good too, but the OP makes it sound like America is a nightmare for the disabled.

You do see my point, you just don't like it.
