Lancair's IMNSHO, are no less safe than any other aircraft, however this must be caveated by the comment that they are much more demanding than most other GA types and require very good training in the aircraft, its behaviour and performance. They do have some gotchas for the inexperienced, however as long as the pilot is aware of these and knows how to deal with them then they are a very efficient and relatively fast GA aircraft.
my 2 cents.
