DOUBLE POINTS AT THE LAST RACE
The idea was that this would keep the championship alive until the final race. Introduced in 2014, it aimed to combat dominant performances from a car/driver combo by making it harder to wrap up the championship early in the season. There were obvious flaws though. The year it was used saw Hamilton and Rosberg battle each other for the championship. Hamilton under normal circumstances would've won the championship before the finale in Abu Dhabi. However, with double points he risked losing the championship altogether if he didn't finish and Rosberg won! Also, why Abu Dhabi is worth double any other race is beyond me.
These new tyres were introduced in 1998 and were hated until their death at the end of 2008. They were brought in to reduce cornering speeds of the cars by reducing the contact patch of the tyre. Many drivers were critical at the time of the feel it gave them. The tyres did not make a huge difference, especially with the development war between Bridgestone and Michelin which only made these tyres faster.
The first, but certainly not the last qualifying rule to be mentioned in this list. Aggregate quali was introduced in 2005 to solve a problem that didn't exist. It meant the drivers did two one shot laps: one on low fuel and one with their race fuel load. An aggregate time was then taken from the two. Surprisingly this ridiculously complicated idea was scrapped before the end of the season.
NARROW TRACK CARS
As well as introducing grooved tyres in 1998, the FIA made the cars narrower. They certainly looked quite strange in comparison. Although everyone did get used to it, it must be said that the wider cars we have again in 2017 are just better!
People are certainly divided on this one, but I'm not a fan. It is a pretty false way of overtaking another driver in my view. Formula 1 is not necessarily about overtaking. Some races are memorable because there was a distinct lack of overtaking. Imagine the Monaco Grand Prix in 1992 where Mansell blasts past Senna because of DRS, memorable stuff...
God I'd almost forgot about this one. At the beginning of 2016, for some unbeknown reason, the FIA decided that qualifying needed changing - it didn't. The timer elimination in quali meant that we ended up with a farcical ending to Q3 whereby the pole position man was already out of his car with 3 minutes of the session left because no one else could set a time. xMattyG summed up all our feelings about this.
The beautiful art of qualifying has received some stinking rule changes over the years. Fuel credit quali was also a massive write off. When the present format of qualifying was introduced in 2006, there was a massive flaw with what is, overall, actually a good way to carry out quali. The top 10 fastest drivers would go into Q3 and then spend 15 mins burning fuel before setting their lap times. They would then get that fuel back before the race. What a completely pointless rule and one that is thankfully gone now.
CLOSED PITLANE DURING THE SAFETY CAR
This was a shocker of a rule used during 2007 and 2008. When the safety car was deployed, the pit lane would close shortly after, until all the cars had lined up behind one another. Then the pitlane was reopen, although the exit wasn't - this saw the infamous collision between Hamilton and Raikkonen in Montreal 2008. It was so unfair to a driver that needed to refuel. He couldn't just run out of fuel obviously and would have to box when the pitlane was closed, so therefore earn a stop-go penalty. So stupid.
A POINT FOR FASTEST LAP
This rule was introduced during the 1950s era of Formula 1. It didn't last long. Inaccurate timing systems - stopwatches essentially - led to its undoing. For example, at the 1954 British Grand Prix, seven different drivers were awarded the single point between for posting the fastest race lap of 1m50s. All earned 0.14 points! Madness.
V6 HYBRID ENGINES
I'm done with people saying that these engines are road relevant. They aren't and it shouldn't matter anyway. F1 is all artificial. It is a show. Yes a technological one too I appreciate, but I can't count many fans who like these lawnmower engines. V10s are just glorious beasts, please lets stop using V6 engines!
