Not in the United States, that's for sure. Gas alone if you're driving 30 miles a day (15 mile commute isn't out of line) means you're buying at least a tank a week - $2.50 x 13 gallons, $32.50 x 4.5 weeks, $146.25. The absolute cheapest liability insurance with no comp and collision is about $75 bucks. So better hope your car is paid off, never needs an oil change, and you never get in an accident for "$200" as you put it.
More realistically, triple or more that dollar amount.
And $400 for groceries? I assume you mean zero alcohol, zero name brands, and zero nights out or fast food - sure you can make that work.
Internet's also closer to $80 unless you're still using dialup or you bundle - but then you're talking $120-140 in most cases.
All of your dollar amounts assume you have ZERO social life and ZERO entertainment expenses like streaming services. Again. Without someone to split bills with, it's simply not enough.
