If you wouldn't put a child in your own car without a carseat, why would you do it in a taxi? Â Just because its legal, doesn't change the laws of physics. Â Its legal in Florida for my 27lb 3yr old to ride in my car in just a seatbelt in the front seat. Â Safe? Â Nope. Â
Â
Speed, traffic, the road you are traveling on don't make any difference. Â An unrestrained child can die or get badly injured even in a minor crash and that could happen any time, any where. Â
Â
A bus is a different matter altogether, crash dynamics are different and they are designed to protect passengers without restraints. In addition, statistics show that busses are FAR less likely to get in a crash, and crashes they do get into are less serious.Â
Â
 Cars are designed to protect properly restrained people, and a taxi sign on the roof doesn't make it safe to go without a carseat under any condition.Â
Â
Â
There are options for those who live in cities where they will be taking lots of public transport - heigher weight limit infant seats that strap to strollers, a couple convertible seats that attach to strollers, travel vests, and for older kids, backless boosters that can be easily carried. Â
Â
Or take a bus, train, subway, bike, walk, or stay home. Â In Vegas they even have rick-shaw things pulled by bike to ride in, and some monarail things between some of the hotels. Â I'd do any of those before putting my kid in a taxi without a carseat.Â
