Speaking to reporters early Wednesday, Tver Gov. Igor Rudenya said that all drones in the region were shot down and that there was a fire on the ground as a result of debris from a downed drone. As he spoke, loud explosions could be heard in the background.

Recreating production cars and racing them is fun.

Optimizing track cars for different locations is a LOT of fun. More power doesn't always mean faster lap times - what matters is power to weight ratio, paired with getting the suspension, tires, brakes, and downforce just right.

The most fun build I've discovered so far is throwing a 2L, naturally aspirated V8 that makes 521 HP, into a Pontiac Fiero with racing slicks. The whole thing weighs just 1159 lbs, and can pull 3 G's around corners.

Apparently they're pushing south from Belgorod rather than directly trying to deal with the expanding area of Ukrainian control south of Kursk.

Bet that would be fun to take off road. The dimensions are similar to a jeep.

Ukraine, Cuba, South America, Africa, election interference, OPEC, and the list goes on.

If the sun became a red giant tomorrow, and Earth found itself inside the outer layers of solar atmosphere, then drag would start slowing it down. In less than 70,000 years, it would fall close enough to the center to be torn apart by tidal forces like one of Saturn's moons (assuming it hasn't already been vaporized).

If we've already waited 5 billion years to have our revenge, whats another 70k? The lowest amount of Delta V we can spend on this project is zero.

Sagittarius A* would like a word, and you'll never get that word back.

What if we catch a gravity assist off Jool, and do the retrograde burn at perijool to gain some free Oberth Effect DV?

I'm skeptical of the problem being that simple. I think if that were the only issue, we would have cheaper cars.

Part of the rational for producing high margin trucks and SUVs is that investors demand the most margin possible out of every unit of production capacity. If a factory can only turn out 100 vehicles a year, its more profitable to turn out an expensive SUV that only 100 people can afford, compared to selling 100 cheap sedans that thousands of people want but you just can't produce enough of them.

If there were overcapacity, then in a vacuum, it would make sense to put it to work turning out low margin cars that are in high demand and making some money with that capacity instead of no money.

But its hard to predict years in advance when your factories are going to have excess capacity, and to know when to begin years long engineering projects so the vehicles you're going to want to produce will have their designs finished in time to fill those gaps. And its extra risky to begin those kinds of long range projects during times of rapidly changing regulations of ICE vehicles, and rapidly advancing tech for EVs that might invalidate years of engineering and factory tooling investments because you can't sell the vehicle you planned to produce for a long enough time to make back your investment and start seeing a profit. Not that I'm anti-regulation - I like breathing clean air and drinking clean water.
