The question is, though - did your iCourier beat Shaye's time for the Liz Ryder circuit in the SRV?
Those SRV times are epic. The iCourier has a nominal top speed around 800 m/s, the SRV a nominal top speed around 30 m/s. So, even considering the iCourier has to go around the circuit thrice, it should leave the SRV standing. Heck, I'd probably need that time just for getting my SRV back into the ship[1].
[1] Wait a cotton-pickin' minute. Is that actually required? All the Engineers (at least Felicity) offer restock. That might be a question to the race marshalls: am I allowed to restock my vehicles (SLF or SRV) if they are errrmmm... accidentally destroyed during the race?
