You can’t compare indoors and outdoors directly. I think random has its means in an uneven environment. It simply doesn’t matter if the odometry sucks, if the wheels stick in muddy earth or small sticks block on side.

Advanced sensors such as GPS and cam isn’t very precise outdoors. That’s why newer models come with its own positioning sender.

Sorry but this is a primary schools‘ view on money. I know this is how it been taught at school and this is entirely wrong.

I wonder how human societies survived without money, if this is so essential for the crap.

I wonder why people do crappy jobs for money? Is it because they need much money for things such as car, smartphone, playstation? For some food, you do not need much money. Actually you can grow it for yourself if you do not live in a big city.

Sure, if one got in this consumption trap, one needs a constant inflow of fresh money.

It does matter. How much worth is helping a friend? Or how much money for your neighbors for caring your pets while you‘re in holidays?

Don’t you think they will refuse to take money for this favor? Not everything in humankind can be paid for.

Same as ever…was that money wasn’t needed.

Do you need money within your neighborhood or your family? Do you pay people for giving a favor?
