the codes are on signs along the side of the track
hit the look left button once or twice it ain't that tough.
time budget WTF
There are those of us that are husbands, fathers and hold down a job and have a many other interests.
In any week I may go shooting, drive my real sports car, ride one of my 2 stroke GP bikes, spend time with my daughter, spend time with my wife and spend time with my dog - do some gardening, fire up the 3D software to continue working on a car or track for AC and rF2, do some mechanical restoration work, fiberglass, play the odd PC game and odd console game, watch some TV, browse the web and still get paid to work a full 50 hours+.
So yes, a time budget.
I took 30 minutes out of a day and drove the entire VIR with Oculus Rift and an open top Willys Jeep to find these stupid easter eggs, and there was only 1 obvious 1, opposite the Oak Tree location.
I did not immediately see any others. And I drove the entire property from edge to edge including infield, kart, out field, restaurants, lodges and access roads.
So no, they are not that obvious or easily visible.
As for the track itself, it was obviously a huge effort and its pretty decent but not the greatest thing since sliced bread. Anything outside of the main venue is unfinished and probably should not have been included as a drivable area as once get off the main venue the lack of polys and detail is very obvious and detracting from the emersion especially if you use VR.
Stick to the main track and its amazing, take a turn out of the hot pits and its meh
