A bit split on Extreme E - spectacular backdrops (future ones may differ), very intense starts, but then a bit of a procession, plenty of media attention, though as AndyRAC pointed out we don't know how long that would continue. Naturally, as a design engineer, I am not a fan of single make series, and obviously competition would have led to a faster rate of technology development, but such scenario is more challenging from budgets point of view. It will be interesting how the Dakar gets on with the new technologies class, it is certainly more appealing to me. Back to Extreme E, I am not entirely sure how the dust slipped their attention and what their expectations were when they set up the series, as visibility was always going to be an issue racing in the sand. Anyway, they are now talking about time trials and from my point of view something like the Isle of Man TT type would work best, with min gaps just to ensure the dust settles. It would also mean the drivers can't afford to relax till the finish, rather than settle for the position they are in knowing they can't overtake/be overtaken. Constant on screen time info is vital to keep spectators informed.
