The shortest war in history, between Britain and Zanzibar in 1896, lasted only 38 minutes
The war was fought over who should succeed the recently deceased pro-British Sultan. A Prince — Khālid bin Barghash — refused to let the British install another pro-British ruler and occupied the Sultan's palace. But when the Royal Navy fired on the palace, sending it up in flames and killing 500 of Khālid's men, that was pretty much all she wrote.
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.
