HPDE1 is effectively the standard weekend entry that is equivalent to six hyperdrives, i.e. six ~20min track sessions and four to six classroom sessions.

Or looking at it another way, a Hyperdrive is equivalent to the first 1/6th of a HPDE1 entry (since it is one classroom session followed by one ~20min track session.)

There is no cheaper or easier way to get on a roadcourse at speed with an instructor riding shotgun...
