- limit on testing means that whoever makes the best car after regulations change will win until next regulations change (2010..2013 Red Bull, 2014.. today Mercedes), others have very limited means to catch up
- scoring system introduced in late 00s rewards reliability over racing, and gives miniscule reward for 1st place: now you get 25 for P1, 18 for P2, and in 80s it was 9 or 10 for P1, 6 for P2, and in 1980s only 11 of 17 results counted towards championship, so drivers would often take more risks to get for results. Now they just drive home safely.
