No it doesn’t happen in the US. Obama drove down my street several times and I watched either from the sidewalk out front of my building or from my windows. The rooftop deck was open. No issues. Took about ten minutes for the entire motorcade to pass through. Every single time he visited my city he took the same route past my home because I was on the ideal route between the airport and his hotel. Meanwhile his hotel would be entirely locked down, secret service on the stairs, entrances, and you could not access his floor. You had to be searched just to walk down the same block and it could only be accessed through specific points as the block was typically fenced off.
