2,000Lbs is a low estimate. 2,500Lbs assumes they drive a subcompact, 4,100Lbs is the current average weight (and 2004 was already at 4K so I'm not sure if this statistic counts SUVs/trucks or not). Even Kei cars are 1500-2500Lbs (ICE versions being lighter, though there are smaller and lighter cars including 2-person EVs that are under 1K*.
I would also add the time spent in a car (particularly in slow/jammed traffic) is also sedentary time (which an office job also likely is) and thus a health issue. So some people buy gym memberships which they must also drive to. If they even have the time/money/energy.
Also lots of bad things to be said about roads(/stroads) and parking lots etc. But the short of it is, they aren't places hospitable for living. Particularly on a hot day.
*=Though this lower-size vehicle may be legally classified as something else, such a a "covered motorcycle"/autocycle (or from what I'm seeing, some other close-enough category) which may be an issue or a boon with laws, and may even depend on local laws.
