All right.
Again, stating, of course, that I'm not an engineer and I'm not at the forefront of what's out there, in a little bit of the reading I did in preparing for this, I recognized there are some potential other technologies that have yet to be really formally validated, such as airbags and things like that.
Unfortunately, in the absence of any evidence to the contrary, I think the system they have now and that's being tested is what's available. As for whether or not there's better technology out there, I can't really speak to it.
