Both my kids were born in Berlin (now 6 & 8 years old) and we never owned a car. In some ways transit is even easier with a stroller as you can just roll into the subway/train instead of having the disassemble the stroller and put it into the trunk. Buses require a bit more effort to board with a stroller but newer busses allow the driver to lower them near the curb to make boarding with stroller easier. We’ve done that for the entire time our kids used strollers.
