You have more civil rights as a pedestrian than you do in a licensed motor vehicle.
Travelling further, without a car, then requires use of public transportation and by using public transportation depending where you are you have implied consent to being searched "for safety".
Acknowledging civil asset forfeiture is a problem in some jurisdictions, private automobiles still provide a greater expectation of privacy than public modes of transport.
Existing on public transit is not an automatic agreement to be searched as you describe.
Here’s an attorney website that describes your general rights:

There are many more things that are illegal for you to be doing as a driver of a car versus existing in public on public transportation. Many of these things can trigger searching your possessions being legal compared to being a person on public transit.
You’re also required to present your drivers license and fully identify yourself if you are stopped for minor traffic infractions like a tail light being out.
As a pedestrian, in most states you do not have to present ID to an officer on the street.
For example, it’s generally not probable cause to search on public transit if an officer smells alcohol, while in a vehicle it’s basically an automatic search of your whole car. You would also have the issue of what a court or jury thinks of the reasonableness of the search based on the context. If you’re quietly minding your own business on the train and you smell like alcohol is a judge or jury going to think the search was reasonable? Now compare that to a driver in a vehicle smelling like alcohol.
Furthermore, the whole concept of a DUI checkpoint where every person is stopped and questioned is at the very least impractical and often illegal for pedestrians.
Thank you for your service as the incorrect carbrain of the day.
I live in central TX and until recently it has been fairly rural. It is now very suburban and it is very common to have to drive 20 miles or so for groceries. There are also lots of traffic lights. For most there is almost no practical way to get to any consumer business on foot and no public transport. Twenty years ago it was "living in the country" and travailing for anything was just part of the deal to live here. It is about the same but with the added joys of traffic, less privacy, and higher taxes.
Most people don’t live in NYC. Transit and urban planning solutions appropriate for there is supremely unhelpful for most other places.
And I would assume you get a small license plate? Similar to e-scooters
