travelling by taxi with infants

Some taxi's have seat belts, some don't.

We also have never seen a baby car seat used in this country. However, occasionally there is a poster who says that they did bring their car seats and used them.

We've taken at least four taxis per day for the past 3 months. I always sit in the back seat, and don't recall seeing one taxi with rear seat belts. Maybe I'm not very observant. What I have noticed is that the power windows on half the vehicles so equipped don't work....and are always frozen in the closed position. (Keeps out the rain....and the fresh air.) And a few taxis with wind-down window handles are sans-handles.....again, in the "up" position. Car seats for children? Nada. Maybe they're stowed in the trunk?
