Well yeah its humans then kangaroos but thinking about it there are a few land based birds like the emu which have also perfected bipedal locomotion, even if they are smaller in numbers.

Also Kangaroos who I would argue are the second most successful land based biped.

Reply to comment by agabwagawa in When a wave travels goes from a higher impedance medium to a lower impedance medium, why would that cause a reflected wave? by agabwagawa
The high impedance medium can carry more energy than the low impedance medium. So when a wave goes from high impedance to low impedance some of the energy is reflected back because it can't go forwards.

Reply to In the twin paradox, what happens if the travelling twin never U-turn to get back to earth? (explanation in the post) by PoufPoal
Astronauts who went to the moon actually did live fractionally longer than people who stayed on Earth because of the speed they traveled at. Its not measurable in this case but it can, I believe, be observed in the behavior of relativistic jets from stars.

There is a fine line between doing things for people and trying to control their lives.

Maybe oil is slowly soaking out of other areas into the places we collect from.

The ability to hot swap batteries would solve a lot of these issues and may be more appropriate in a commercial context. Build it in to your workflow and have dedicated swap points every hundred km or so.
But if the battery is 60% the value of the truck...

They are saving 20 bucks on switches this way. And switches are one of the more durable things in the car. Unlikely to fail during warranty.

Yes but only a few which are primarily land based, and capable of covering ground as well as a kangaroo or human. Emus, ostriches, and a few others.
