The Aztec capital Tenochtitlan (where Mexico City now stands) was larger and more sophisticated than many European cities when the Spanish arrived in 1519.
With an estimated population of 200,000–300,000 inhabitants, Tenochtitlan was significantly larger than London (which only had 50,000–70,000 people), and Paris (about 200,000).
Tenochtitlan's infrastructure was better, too, with advanced aqueducts, causeways, floating agricultural fields, and even efficient waste management systems.
The Spaniards' siege and the aftermath all but destroyed the great city that was.
If we used hovercraft instead of wheeled vehicles, we would not have to waste tens of billions every year building and maintaining roads; we would just need a few guardrails here and there to protect landscaping. And no need for spreading salt and brine to melt road ice because the hovercraft would basically treat all surfaces the same, whether lawn or snow or water it would make little difference.
Also, damage from accidents would be negligible, so insurance rates would be minimal.
Not to mention that squashed critters due to tires running over them would be a thing of the past.
So it seems like the Aztecs were ahead of their time.
