Agreed
,just as the Speedsource boss developing future Mazda LMP2 for ALMS(USCC) said, we need more campaign to tell others this is not only a hardcore fans' business but it's relevant to everyday road car,
though the first Gen hybrid prototypes are actually borrowing the ERS system from F1 IMO.
The R18 bought the flywheel system from Williams after their air hybrid banned (Peugeot is, in fact, developing similar air hybrid on road cars). Meanwhile, the super capacitor ERS on TS030 is actually the dominant form in F1, apart from Williams' flywheel. Pity that Williams moved to super capacitor as well.
2014, however, might be different with Porsche building their in-house ones. We can expect factory engineers improvising various new technologies as well as exploiting the most out of incumbent super capacitor and hopefully no more discouraging bans again.
