1- F-1 & ALMS. Both are showcases for high tech.
2- All the time. I also tape them to enjoy them later.
3- On TV I watched F-1 whenever it was televised. On speed tv I watch it all the time. In person I watched GP racing at the 1957 GP of Habana. Saw Fangio win, Stirling Moss and Marques de Portago as a kid with my father. It was loud and no ads on cars at the time. Lots of Ferrari's, Maserati's and Alfa's. Next time at Watkins Glens when Alan Jones became champion with a Saudia- Williams. Ferrari was no good then. I attend the GP of Canada in June. I take my son and son in-law.
4- Drivers I enjoyed watching would say: Fangio, Senna, Schumacher, Raikkomen & Giles Villenueve, the father. Can not forget the GP of France in the eighties and watch Villenueve in his #27 Ferrari go wheel to wheel with Rene Arnoux in a turbo Renault for second place. They banged wheels at 200 mph on a long straightway. Arnoux conceded the position to Villaneuve ended in third. Teams, I like Ferrari, Williams, McLaren, Audi in ALMS series,
5- Nascar & IRL. Have total disdain for going around in a circle.
