IMHO, one should not dwell on crash protection in a Europa but rather collision avoidance. Our Europas (as well as all other lotuses) maneuver extremely well and demand constant attention when being driven. We just have to try and avoid getting involved with all the land yachts with their drivers preoccupied with texting, futzing with the infotainment systems, while sipping their lattes. Try that while driving a Europa!!
BTW, I had a motorcycle many years ago. At the time I was given this sage advice: when riding, pretend you're invisible; you'll live longer! I use the same mind set when driving my Europa.
I guess if one is prone to exploring the limits of the envelope in a Europa, one should consider enhanced crash protection. Just saying..
