I have watched the video yet but crash safety doesn't surprise me at all, nor does service life, reliability, performance etc.
Where I think older cars, bikes, machinery would come out on top is where you park a half worn modern car along with a half worn old car in storage for 40 years and then compare which one requires the most among of resources to get it going again. The old one will need a battery and maybe some cleaning up of the fuel and ignition systems and it will be made mobile by an joe with half an idea of how their lawn mower works. As for the modern stuff, have fun!
We bought a farm many years ago and it had an old McDonald single cylinder 2 stroke Diesel engine on it. Before the machinery preservationists came to take it away they wanted to start it. After toppi g it up with oil and fresh fuel and making sure the flywheel would turn it started just like the last time 40 years prior when electricity made it redundant. A modern diesel with its electronics might be doubtful after 40 years of weather, vermin and deteriorating plastic.
