Finnair have these videos on their new 'buses.
Yes, I am so used to NOT seeing them that after watching the safety info with the funny American sounding bloke I went back to read during taxi, then we were at a holding line.
Then for some reason my brain recognised seeing an aircraft whizz right in front of my eyes, yet all the other recognition stations said that it should not happen ! It took a few intervals to realise that it was on the screen ahead and that it did, in fact, correlate to what was happening l and r.
Nice to see ! Not sure what company procedures are as some switch off on taxi. Some dont and it did amuse nearby children to see the funny man "waving" at the aircraft (!) as we came to the gate.
