On Velocity Saturation

Say if I lived in Mountain View and my workplace was in Cupertino (what a paradox!). Anyhow, it’s December of 2021 - everyone is relaxed, so I don’t have much “force” of getting to work at dot 9:00 am from home, well because we have a laxed project routine. So, my commute would be stress-free even with bumper-to-bumper traffic on De Anza college exit; I can travel at 45 mph and still get at work due to lenient “force of attraction” to work desk. But say it’s August of 2021, 6 weeks before major hardware launch. Whether I intend to drive at 55 or 65 mph or even eye tearing 75 mph - IT DOESN’T MATTER … because I’ll be severely limited by bumper-to-bumper traffic between 8:00 am and 9:00 am … … … if I drive at 55 mph, maybe I might have a low probability of having traffic collision, but at 65/75 mph with higher speed, comes higher probability to collide with a car in-front of me. No matter whatever I do, and the dire “force of attraction” to reach work desk by 9:00 am, no speed would matter, because the probability of collision would increase with increasing speed. Whether I drive at 55/65/75, I am just gonna be slightly earlier to reach at work with increasing speed, than the jump from driving at 45 mph to 55 mph (because cars may very well be driving between 45-55 mph, but if I drive at 65/75 mph, I’m gonna be bottled-necked by 45-55 mph of average moving traffic). That’s the concept behind velocity saturation - whatever speed you drive at, thanks to relatively slow speed of other cars, you are never gonna make it to your workplace at 9:00 am, even when driving at 65/75 mph, if you leave from home at 8:45 am, while the maps shows an ETA of 9:15 am at 45-55 mph average traffic speed consideration.

On a side-note: I often come across people with fallacy that electrons travel at a speed of light within conductors; you certainly don't expect electrons to travel at speed of light, do you[1]? Believe it or not, but more often electrons "travel" much slower than the average speed of snail - by roughly 600 times slower than the slowest known creature we always ascribe to being "slow" (hint: drift velocity)
