Please look up Fahrerlaubnis-Verordnung (FeV) 6:

Klasse B:
Kraftfahrzeuge – ausgenommen Kraftfahrzeuge der Klassen AM, A1, A2 und A – mit einer zulässigen Gesamtmasse von nicht mehr als 3 500 kg, die zur Beförderung von nicht mehr als acht Personen außer dem Fahrzeugführer ausgelegt und gebaut sind (auch mit Anhänger mit einer zulässigen Gesamtmasse von nicht mehr als 750 kg oder mit Anhänger über 750 kg zulässiger Gesamtmasse, sofern 3 500 kg zulässige Gesamtmasse der Kombination nicht überschritten wird).

If they state that they're using their car for private needs and then go on to use it in a business setting - certainly.

Over here, you insure the car instead of the driver and you also have to tell the insurance company what you're using the car for. Lying to insurance companies was always a bad idea, y'know?

It's a grey area and the companies you link already have had some problems. However, the companies themselves already link the limits on their sites themselves:

  • No cars with more than 9 seats
  • No profit making - the money you collect may not exceed the costs you incur for gas and car usage (deprecation)
  • No regular routes
  • No drivers who make this kind of driving their job.

The linked article lacks one important detail: The fine of up to 250,000€ is for each instance of breaking the injunction.

Sure, the first violation may only cost 2,000€. But that will go up for every violation. And you can bet your ass that the competitors will use the apps to check on Uber. And they will report any violation they find.

You're wrong there. The VW Up exists as both a pure electric and pure gasoline version. The difference in price? 10,000€

That's the price for the battery. In the case of the Up it almost doubles the price (from 12,000€ to 22,000€). And "all the other bits" being expensive? Seriously?

With the switch to pure electric you just god rid of the following: The alternator which provides the energy for all the gizmos in a normal gasoline car. And, more importantly, the transmission, one of the most complicated and intricate mechanical pieces in a car with a combustion engine.

Two complicated parts of the car, just poof! gone like that. The engine itself also just became way more easy - you don't need carefully timed pistons. You don't need the 3-way catalysator and the lambda probe. And so on and so forth. Hell, if you wanted to you could let each of the 4 wheels be driven by a separate motor! (which gets rid of the need for a differential!).

Yes. But they're not cheap and the production process is quite involved. And he specifically drew a relation between material used and possible aerodynamics:

[...]Replacing metals with ultralight, ultrastrong materials like carbon-fiber composites can provide safer, lighter and more aerodynamic vehicles that consume severalfold less energy and could be simpler to produce with 80% less capital.[...]

From:"Reinventing Fire: Three Energy Gamechangers for China and the World, Nov. 15th, 2013, pg. 2

He specifically mentioned "more aerodynamic" in addition to "lighter". I'm also not that convinced of "ultrastrong" materials being safer due to the fact that you want a crumple zone to soak up kinetic energy.

Not to mention that "severalfold less energy" is a lie: The BMW i3 already largely consists of carbon-fiber and is not that much lighter and, if you calculate the average energy consumption, doesn't consume that much less energy.

Lastly, carbon-fiber is not more "simpler to produce". Folding, bending and melting metals is easy compared to what you have to go through for carbon-fiber. Not to mention that it's not recycleable. Metal is easy to recycle.

Well, that's the problem with most renewable energy creators: They're dependent on an external factor. So, keeping some in "reserve" might not exactly yield the result you want. What use are additional windmills is there's no wind? What use are solar panels if it's nighttime or overcast?

Yes, there are others like biogas or waterpower, but most of those would fall under this heading of "energy storage" which this guy proposes to be superfluous. If they aren't storage technologies, they're usually not scalable enough, either due to provisioning problems (biogas) or geographical restrictions (water).
