glad ur ok.
accidents happen, and urs certainly came along in a big way!
its spookily similar to mine, in that i crashed at 50ish into a ditch, luckily my turned end on end, not over like urs.
both of us got off lightly with the injuries... in any normal thinking.
no car is a black box, but the elise comes v close to it

id feel safer in the elise than a normal car, except vs a lorry!!
its nice to find the interior staying put - coz thats where u sit
hope u get whatever result makes u happy.
and decisions can be undone by other decisions, so whatever u do it wont be the end of the world if its wrong
my doctor said i should have replaced my 111r with an exige - only coz it had a roof to protect me from the grass and bushes that brushed my hair in my crash

lol!!
