  • Daily Coping 11 Oct 2022

    Today’s coping tip is to take a small step towards a goal that matters to you.

    I’ve been working on a coaching certification. I don’t really need it, but it will help in the future if I end up changing to a new club or role. I’m trying to take time every few days to work through a video and a quiz.

    This is a good reminder to keep doing that, so I’ll watch one tonight.

    Today’s coping tip is to write down three things you can look forward to in the next month.

    Easy.

    1. Visiting my daughter. I’m heading up this weekend to watch her play and hang out
    2. SQL Saturdays – Boston and Toronto, exciting to get back to a few events
    3. Open Gyms – Volleyball won’t start for another month, but I have a few gyms I’m hosting for kids that aren’t playing now. Looking forward to seeing them out on the court.

  • No Autopilot in the Tesla

    Recently I was driving home and I couldn’t engage Autopilot. I kept seeing the availability icon come and go, and found this interesting, but also a sign of why Level 4 or 5 is likely hard to solve in a general way.

    This is part of a series that covers my experience with a Tesla Model Y.

    Denver Sun

    When I first moved to Denver, I was driving down I-25 early one morning. There was a stretch that turned East and was blinded. It felt like the sun was directly in front of me on the horizon. This is something that I’ve gotten used to a few times a year, as the sun seems to be at a lower angle than I see anywhere else in the world.

    My Tesla Model Y, Long Range (MYLR) apparently had the same problem this week. I was out early to town and ended up coming home around 8am. Driving East, the sun was low and seemed to be coming directly into the car. Fortunately it was slightly to the right, so I could see straight ahead. This is a section of road that I often engage autopilot as it’s got some ups and downs, is fairly quiet with a median, and I like letting the car control the drive.

    However, when I engaged Autopilot (AP) I got the alert that it wasn’t available. I glanced down and saw the icon, which indicates AP is available, so I assumed maybe I’d done it at a place where there weren’t lines. The icon disappears in intersections or other places where the car doesn’t see lines immediately.

    I tried again and the same thing happened. As I glanced down a few times, I’d see the icon come and then go. I looked out and realized that I could barely see the lines in the center of the road because of the glare.

    This continued for a few minutes until the road turned left further and a large hill shaded the road. I engaged AP and it handled the rest of the drive out to the road that turns toward my house. Once engaged, it seemed to do well, even on a few hills where the glare was strong, though not as strong as it was leaving town.

    Radar and Lidar

    There are a number of situations and places where I think that lack of radar or lidar would help. This isn’t one of them. Unless radar is painting the painted lines in the middle of the road, it wouldn’t solve this problem.

    Conclusion

    In a city, or even suburb, where the roads are well mapped, this might not be a problem. In a neighborhood, or place where cars might park on the street, then perhaps radar could help, but vision is vision, and it’s not something that a computer can necessarily do better. Humans make mistakes with glare and blinding light, and cars that depend on vision can do the same thing.

    Actually, I think the recognition of visual artifacts ( shadows, glare, etc.) is slower and more difficult for computers than humans. Humans will also make mistakes, but like many, I think I have less tolerance for computers making the same mistakes. Not sure that’s rational, but I do feel that way.

    This is a reason that I think L4 or L5 isn’t easy, or likely, outside of highly mapped and geo-fenced areas.

  • Daily Coping 7 Oct 2022

    Today’s coping tip is to be willing to share how you feel and ask for help when needed.

    This has been something that I never did well. My parents and others I respected as a child taught me to suck it up, work through issues, be strong and independent. All good qualities, but as with anything, you can take this too far. I think far too many people of my age and older did a poor job of sharing their feelings with others. We also struggle unnecessarily by not asking for help.

    I’ve learned that sharing feelings isn’t bad. I’m not less capable, nor am I less of a professional, coach, husband, father, etc. I can still be accountable for whatever and not like it or not feel good about something. I can also ask for help when needed.

    I’m getting better about providing feedback to others in my life without griping or complaining, at least, I think I am. Recently I’ve pinged a few people to let them know that I do need help prepping for some work things because I’m busy, and because I need help in ensuring I have my schedule correct. With all the things I do, it’s easy to lose track of sessions, deadlines, and more.

    The pandemic has taught me to better let people know how I’m doing, and if I’m overwhelmed, ask for help.
