The FIA has made some changes to the F1 Regulations for 2015. These were put forward by the F1 Strategy Group, passed by the F1 Commission and agreed by the FIA World Motor Sport Council. They are designed to cut costs. There is nothing of great significance, just fiddling with the rules with reduced testing, reduced wind tunnel time, reduced CFD and so on. The only significant change from a spectator’s point of view is that Safety Car restarts will now feature standing starts, unless it is within two laps of the start (or of a previous restart) or within five laps of the finish. The design rules will change to make the cars less ugly.
There is also a change of rules that mean that the sporting and technical regulations for the following cannot be changed without unanimous agreement after March 1 each year, rather than the current June 30 date.
The logic of having standing starts for restarts is beyond my comprehension as standing starts are generally more dangerous than rolling starts, although they do provide more chance to alter the running order. thus one can only describe this idea as one that increases the risk of an accident in an effort to spice up the show.
