    Our eyes are not perfect organs so why pretend like they are? Our eyes fail us:

    • when it’s too dark
    • when it’s too bright
    • when there’s fog
    • when there’s too much rain and snow
    • when there’s glare from the sun
    • when there’s obstructions
    • when there’s sensory overload
    • when there’s something covering our eyes like dirt and mud
    • when we can only see on the visible spectrum

    Why wouldn’t we want more incoming data to account for these shortcomings? Optical-only vision-based solutions are incomplete because our eyes are incomplete. I can’t see that a car is stopped dead in the road 10 feet ahead of me in thick fog, but an advanced set of telemetry sensors can. My eyes are not better than the scores of technology we’ve built over the past few decades and I’ve been practicing with them for 46 years. Give me a helmet that includes LIDAR and infrared and night vision and sonar and telemetry from a satellite and GPS and weather tracking and god knows what else and I’ll be much less likely to rear end that car in the fog. We humans invent technology to make up for our shortcomings, so why go with the idea of “if it’s good enough for biological evolution it’s good enough for these multi-ton contraptions we have hurtling down highways next to each other several metres apart at 100 km per hour every second of every day?” It sounds ludicrous on its face. We can choke on a peanut because our swallow tube is the next to the breathing tube ffs. We can do better.

    I watched a tourist drink a few beer at the local inn and then just throw the cans onto the lawn and keep drinking. So basically littering. That stuck in my craw. This is my town buddy, take the 5 seconds it takes to dispose of your shitty cans of your shitty mass produced beer that you usually have back home that you made sure to let everyone is far better than the local microbrew we have here in town.

    Also one time we had some tourists loudly complaining about immigrants while visiting. Those aren’t immigrants you dope, they’re citizens of our country. They were born here.

    On one occasion I was driving somewhere and it was along a scenic drive and I had to stop for something. A group of aging old men on motorcycles who were doing the scenic drive told me I couldn’t park in that area because it was theirs. I said get fucked, you’re in my backyard, I’ll park wherever the fuck I want. I think they thought they were intimidating because they fancied themselves a biker gang, but biker gangs usually don’t have New Balance and rental bikes as part of their aesthetic.
