There is no anchor point and it is not appropriate to install any car seat in the roadster. The airbag cannot be disabled and it is unsafe for any child to sit in the front seat.
Just to clear up a few things. I think the perceived danger of air bags, seat belts and motorcycle helmets are exagerated. I'm a trauma surgeon and have seen a plethora of motor vehicle injuries. I
have seen very serious injuries and fatalities as the result of airbags and seatbelt use, but the number of saves WAY outnumber them. The airbag study involved 1.8 million deployments. It was determined that 2620 people survived as a result of the airbag and many others avoided more serious injuries. There were 38 adults and 49 children killed, most of both groups were improperly restrained or positioned. Most of the adults killed were drivers and obviously, all of the children killed were passengers. That's where the misconception stems from. But, 12 of the children were in a rear facing car seat, 4 were on the lap of an adult, 25 were
completely unrestrained, and the other 8 were wearing their belt improperly or not in the proper child seat.
It is
recommended that children under 12 ride in the back. Some state or local governments may say otherwise, but it's not a federal law. The key to successful air bag use is being far away enough from the airbag to allow it to deploy, prior to hitting it (>10"). A rear facing child seat should never be used in the front, because they are already too close. Children should never sit on the lap of an adult. Not only are they too close to the airbag, but they are more likely to be crushed by the adult. Everyone should wear a lap
and shoulder belt. Children should be in a properly sized booster.
I regularly transport my 5 and 8 year olds. I have no intention of installing an air bag switch. I leave it up to each of you to decide for yourselves based on the data.
