And if you are crossing terrain which rises above the SE ceiling of the twin (for a significant distance) then you have a 2x (min.) chance of crashing into it, than with a single. Admittedly that is an unusual case in Europe (the Alps take only ~ 45 mins to cross, N-S) but twin owners do like to use mountains as a common example of twin advantages.

Dont understand some of the above? Why do you have 2x the chance of crashing into them? are you basing that on the fact that you have 2 engines hence 2xs the chance of one failing. Ok accepting that you have one fail you will be going down as well as forward and hopefully forward to lower terrain if you know where you are and head in the right direction!
On the non turbo twin you will be going down albeit at a small rate with the remaining engine producing power.
As the non turbo descends that descent rate will decrease until at about 7-8K the aircraft will fly level.
Take a Seneca five light twin with turbo charged and intercooled engines and it has a single engine service ceiling of approx 16500 feet good to clear all the mountains in Europe.
The poor single will GO DOWN and down into whatever so cannot understand your 2Xs in a twin?
That sounds very much like a singles marketing statement and NOT accurate
And remember even over the Alps while there might be spot heights up at 16K the everage will be much lower with valleys much lower still.
