Hi Daniel!
For true one hand folding, practice the sequence until it becomes instinct. Do a few slow reps with two hands, then try with one while your other arm holds a pillow or the baby in a carrier. Set the brake first, then fold and see if the release is a single squeeze, if the frame collapses without wrestling the wheels, and if an auto lock engages so it stays shut. Try lifting it to trunk height and back down with one hand and check whether there is a carry handle or balance point you can grab without fishing around. Do a quick real life drill in your driveway by timing the steps from car door open to stroller folded and stowed. If any step consistently takes two hands, that will feel frustrating on busy days.
Uneven sidewalks come down to technique and maintenance. Lock the front wheels on rough stretches so it tracks straight, then unlock for turns. Lightly tip the handle toward you to float the front wheels over cracks rather than plowing into them. Keep the wheels clean and spinning freely, pull hair or lint from the axles, and add a tiny bit of silicone spray to moving parts. If the tires are air filled, keep them firm. Take shorter steps on broken pavement to stop the jitter, load heavy items low in the basket instead of the handle to prevent tip overs, and use the wrist strap on hills. For a newborn, make sure the seat reclines flat or has proper support and keep the harness snug. Test your usual route for a few blocks, note any spots that bounce, then adjust speed, wheel lock, and how much you tip the handle until it feels smooth.
