Damn, impressive, they even found a chariot from back then (although it looks more like a modern car - you know what they say “what goes around, come around”). For those planning to bury their ‘hardware’, don’t bet on it being very difficult to find.
The move from carts (oxcarts and whatnot) to the chariot (circa 4000 years ago) must have been like the leap from four-door hardtops to two-door convertibles.
