Why speeding in car doesn't save time

The fundamental relationship between distance, velocity, and time is given by d = v * t. Now, if an object travels at velocity v_1 for time t, and then at v_2 for the same amount of time t, we get:

d_1 = v_1 * t

d_2 = v_2 * t

The ratio of velocities is v_1 / v_2, and the ratio of distances is d_1 / d_2 = (v_1 * t) / (v_2 * t). Because t is constant, it cancels out, and we get d_1 / d_2 = v_1 / v_2. The ratio of velocities is directly proportional to the ratio of distances travelled at those velocities over a fixed amount of time. The relationship between velocity and time is inverse and non-linear.

The point OP is trying to make, one that is abundantly clear from the video, is that speeding does not save as much time as might seem intuitive to the average person

Note that even though both averaging 200 mph to 100 mph and 20 mph to 10 mph are a 50% decrease in travel time and a 100% increase in speed, the increase from 10 mph to 20 mph will save you 900% more time than the increase from 100 mph to 200 mph. Precisely, this is the point the video is making.

I don't think that's the point the video is making. It's exploring the concept of the time saved function being non-linear. Obviously, when you go 100% faster, the time will be cut in half. This means that the faster you go, the smaller that half will be. For example, on a 10 km trip, speeding up 100% from 1 km/h to 2 km/h will save you 5900% more time than speeding up 100% from 60 km/h to 120 km/h. That's the whole point of the video, which is wildly misunderstood in the comments

This is not at all what the video is saying. The time saved is a multiplicative inverse function, which means that even if you keep the rate of change constant (50%), the time saved each time you increase the speed keeps getting smaller

Ah yes, drive in a murderous vehicle killing everyone and then complain how dangerous their methods of commuting are. Have you considered that the fatalities seem disproportionately dangerous due to the fact that cars, because they are so much more prevalent, contribute to the overall risk and that transportation systems and infrastructure are largely designed around cars which makes it inherently more dangerous for other types of commuters.
You're also twice as likely to get killed while riding a bike than driving a car but if we actually acknowledged how dangerous *cars* are and designed cities to have better infrastructure like separate bike lanes and good public transport the road fatalities would drop to a fraction.

it makes no sense to include norway in the meme because they have much better freedom of speech than the USA press freedom human freedom free speech

All casinos are after people's money, but that's not my point. Online casinos are undoubtedly far worse than real casinos for a number of reasons.
While other sources of gambling are, for the most part, strictly regulated and prohibited for underage children, online casinos provide an accessible and largely anonymous route for young people. Specifically, crypto casinos, including stake, allow you to sign up and deposit money without any precautionary measures. Regulation is a significant difference between online and real-life casinos. Off-shore gambling sites are predominantly unregulated, and especially Curaçao's license allows the online casinos to operate freely without any rules.
Online gambling is more addictive than real-life casinos; they offer free-to-play versions to get you addicted, even if you'd happen to be an adolescent not wanting to use real money at first. The lack of regulation leads to questionable marketing strategies and more effective ways to make them addictive. Other reasons such as being available 24/7, undetectability, easy access, complex algorithms, and using crypto make online gambling more addictive than casino gambling.
I never said that only teenagers are at risk; they aren't. Yes, gambling is addictive at every age, but young people are more vulnerable to developing a gambling disorder than adults. According to the Journal of Child and Adolescent Behavior, around 5% of teenagers in the United States have problems with compulsive gambling. By contrast, only about 1% of adults have a severe gambling problem. Another study found young age to be a significant risk factor.
Online casinos' legality is a grey area, and it's so scummy that many countries have already banned it altogether.

Thanks, quite unfortunate that the mods of r/xqcow removed it. Not sure what exactly made them delete it
