Suggestion: Open testing or 'Test Day' mode to add to the Proving Grounds section. Why: I feel the developers really added an extra element to the racing in F1 2013 with tyre modelling and I felt having the ability to drive conservatively to save tyres added a whole new dimension to the gameplay - especially in longer races. I'm one of these sad people that gets a lot of pleasure from spending an hour or two doing multiple laps around a circuit, trying out different settings, setups and driving styles to see how I can improve my speed. I've even set up a little spreadsheet for myself where I log my laptimes and check how different setups affect my average laptimes and tyre wear, because I really have nothing better to do sometimes. The only issue is that tyre wear is really important in 2013, but the only way you can test or experiment with settings is in either a race or free practice in Grand Prix or Career mode. Time Trial mode is good to try any car on any circuit, but the track and car settings in Time Trial mode aren't comparable to what they are in a real race situation, plus there's no tyre or fuel degredation as Time Trial mode is all about absolutely laptime only. You could always practice in the Free Practice session in a Grand Prix or Career mode race weekend, but then you have the potential for 21 other cars to get in the way. If you want to prepare for an online race, for example, it's not always ideal to practice in a FP3 session in Grand Prix mode. I think it might be a really good idea if 2014 could include an additional mode in Proving Grounds which would allow us to practice on a circuit with full fuel and tyre degradation so you can have a proper test of settings and setups. You can do this in the NASCAR: The Game series with its 'Track Testing' mode, which will even give you in-depth stats about laptimes, tyre wear, max speed, average laptimes, etc and will even separate stats between different runs so you can see exactly what sort of settings are working better for you with no spreadsheet required! I appreciate the developers have a lot of ambitions about what to include in the 2014 edition and beyond so this might not really be all that important, but I feel this is just one simple addition that might be appreciated by a fair amount of players if it was included.
