Great video! I like how you focus not only on the sport itself, but more on the technology and its impact on the "commercial" car market. I'd like to emphasize on the topic of regenerative braking (RB): Yes, Gen 3 is pushing the benchmark even further, but F1 did the babysteps for it, by implementing KERS (Kinetic Energy Recovery System). Meaning: It is not totally new, but yes Formula E does bring it to the next level. Now, whats really interesting, is how RB is already the standard for commercial cars: PEVs, PHEV and Mild HEVs are totally making use of this, which has many benefits. One very crucial benefit (beside recharging your battery of course) is the reduced usage of friction brakes. Modern PEVs are able to brake more than 80% of all brake events via the electric motor and therefore abstaining from friction brakes. Which brings the crucial benefit: EVs emit WAY less brake particles than ICEs. Which is huge, since the current regulation draft for brake emission particles may makes it impossible for ICEs to reach the threshold values. So, car OEMs need to electrify their cars or use expensive brake pads which wear less, so their cars meet the regulations demands. In other words: ICEs are getting less and less attractive for OEMs, even through back doors like brake emissions.

Two thoughts. First, the main video is excellent. I admit I'm still primitive in that I keep thinking of value as the result of scarcity and provenance, rather than just the existence of demand. Therein lies the difference, I think, between a real, sustainable market and the tulip craze of the 1600's. And by sustainable, I don't mean anything environmental. I mean robustness: can/will the market collapse? No one buys pet rocks anymore. Second, and more importantly, the last bit, about future ads, was just outstanding. You captured the two crucial points underlying sponsored content: (i) that the speaker does what the ad makes viewers think, namely believe in the information presented, and (ii) that nevertheless, since the ad does reflect input from the sponsoring company, it will always make clear that it's an ad. Speaking of transparency: I'm Cleo's Dad.

I've been working in the fracking industry for 17 years and I love that you did this video to bring up some of the ways fracking could be used to make things better going forward.
A couple things to add for those who are interested:
1. One step of fracking that many don't seem to touch on when explaining is that it's not simply fracturing or cracking the rock under pressure that leads to the increased flow. The key step is that a material needs to be pumped down that can hold the fracture open after you've stopped pumping at high pressure (called proppants). Without this, the fractures simply close back up and nothing will have changed. For oilfield jobs, the proppant is typically sand of a specific size range that optimizes the space in between the grains to allow faster flow of the oil or gas you're trying to produce. Because you have to pump sand or sand-like material down into the reservoir, you need a very viscous fluid to carry this slurry, which is why all the problematic chemicals are used for fracturing.
2. I'm not sure about the details for geothermic fracturing, but I'd imagine the wells are deeper and hotter than an oil/gas well and you may need a material more durable than sand for these applications, like a ceramic grain. This might be why we're struggling to do this economically, as these ceramic proppants are very expensive. This is in addition to the pumping equipment required to perform the job, which can regularly cost $250K+ to rent.
3. Still, pushing for more geothermic fracking would still be very beneficial for the world going forward and would allow many of these oilfield workers to keep their jobs, which is one of the biggest concerns that Republicans bring up when trying to defend the oil/gas industry. Taking that talking point away easily is a very big deal.

IMO I dont think this video really gives enough credit to Tesla FSD Beta, or really explains the different approaches to achieve Full self driving. A company like Cruise uses both Lidar and cameras, which overcomplicates things. And are only accesable in geofenced locations, where the AI is "familiar" with the roads. Whereas Tesla FSD Beta only uses computervision, to be able to navigate in the real world, like a human only using vision. The revolution happens when Tesla achieves FSD lvl 4, it will overtake all the competition, because it will be able to drive everywhere, instead of only driving on roads it is familiar with. Incredible we had to watch 2 min of the video before we even see the Tesla logo, even though they are the unassailable leaders of this technology lmao. Most journalists for some reason, completely undermine Tesla and the disruption they have created.
