IMO. these ads are more persuasive than a portraying the products in only good light. Recent psychological studies shows that if you push too much, people tend to not believe you.
So the people who made these ads have done their homework
You may be familar with the BBC TV programme, Top Gear (it is syndicate in dozens of countries, I understand). They did similar tests on a Toyota pickup.
I can't remember them all, but I remember the penultimate test: leaving it on the beach at low tide and letting the tide come in. I also remember the last test: leaving it on the roof of a tall bulding and blowing up the building. There are two important differences, however:
i) all the tests were done on the same vehicle
ii) (after some minor tinkering) the Toyota pickup passed all the tests!
