I know several other people already commented, but still I want to add my own view because this pains me.
I grew up in the 1970s/80s in an area of two 35 thousand people towns (plus lots and lots of smaller towns and villages - rural but it's still all densely populated).
We had all the freedoms to go anywhere except doing school hours - as long as we didn't drive (pretty far) to the German-German border area. Which I would not even have been able to point out the direction. I was in the forests and out alone ALL THE TIME, and so was everybody else. I also was a "key child", this too was very common, I had a house key and was left alone in our house all afternoon, and again, that was common.
Independence, education, sports - the East did not want to raise feeble people. Daily life was NOT some dystopian thing. Youth life was full of biking around in the afternoons, visiting friends all over the place or into the fields and woods, weekend parties, and we were mostly left alone, by parents too.
When I visited the US for two months, driving around in an old car I had bought (~20 - rental car was too expensive for that long, surcharge for being young too) - and sleeping in it most of the time. My impression afterwards was that the US was quite the police state. Sleeping in the care alone, never mind driving in an old car near the Mexican border once, got me lots of friendly meetings with ne police friends... never had any problems and it was all friendly, with my German passport and my story of driving from New York to Alaska to San Diego to Key West to Washington D.C. and lots of loops for scenery and NPs on the way, but I don't think I had a SINGLE encounter with East German police in all my life. Okay once, visiting the East Berlin airport, when I was with a friend who looked "non-standard", they only checked his ID and nothing from me.
And when I saw "Employee of the Month" parking at the very first McDonals I drove by in my new (old) car I could not stop laughing. THIS was sooooo East German! And we even had jokes about it, assuming such a thing would never exist in the West! And here I was in the capitalist mother country and saw a key component of "socialist" worker life.
