> many regular-sized cars cannot fit three child seats in the back.
We have this simple Walmart one [1] and it's 17" at the widest point. To fit three across, then, you need a car with 51" "shoulder room". Most small cars do have that much room:
* Toyota Corolla: 52" [2]
* Honda Civic: 55" [3]
* Honda Fit: 53" [4]
* Kia Forte: 55" [5]
Yes, it's possible to get big bulky seats, but if you get relatively narrow ones they'll fit across the back of ~anything.
