I just had my tires filled with nitrogen to address #1. They claim that it doesn't expand and contract with the temperature, but Physics Brain called bull on that. I do, however, believe that it doesn't expand and contract sufficiently at human-tolerable temperature ranges that such change would cause safety issues.

Never had anti-skid. Wonder how that works.

And yes, ABR is disturbing. For those of us who learned to drive without it, the hardest thing is to remember to NOT take your foot off the brake when that happens. Trust the system because trying to bypass it will make the problem worse. That's why I had a minor collision a few years ago.
