Good post, it never would have occurred to me that car companies would take advantage of a necessary safety feature for infants and toddlers. I wonder what each rental companies policy is on car seats. At many airports they have 3-5 different companies to choose from. Before having a kid I would\'ve made my decision based on which one has the most bad-ass vehicle available. Now, if one of them provided complimentary (or the cheapest) car seat I\'d go with them.
