Hey
@diplomat33, first, I want to say thank you for being willing to look at numbers with me. Other people in this thread have accused me of just having negative opinions, but numbers are real.
You are extrapolating that the number of smart summon accidents will be steady for the whole year. I don't think you can make that assumption.
Why not? What's going to change? If anything, I'd expect Smart Summon users to become more complacent, and accident rates to go up.
I think my method is better because I am just taking the total number of accidents divided by the total number of smart summons attempts.
Neither method is better, they are just different. We can find common ground if we agree on the methodology. Would you like to be so... diplomatic?
You're talking about each individual parking lot traversal, each individual use of Summon -- i.e. there's only a 0.0018% chance of an accident for each Summon. I agree with this. Your number is plausible.
I will need to convert my data so that is also in terms of the chance of accident per parking lot traversal.
Americans take
1.1 billion car trips a day.
Each trip likely involves two parking lot traversals, so Americans traverse 2.2 billion parking lots per day,.
That's 8.3 trillion parking lot traversals per year in the United States.
There are 50,000 parking lot accidents per year in the United States, as I've noted above.
That's an extremely low chance of 0.00000622% of an accident per parking lot traversal.
That means Smart Summon is possibly almost 300x worse than human drivers, in terms of the probability of an accident per parking lot traversal. Even if only half of car trips involve a parking lot traversal, Smart Summon is still 150x worse than human drivers.
The fact that Smart Summon keeps failing in ways that humans usually don't -- hitting curbs, driving on grass, etc. -- is telling.
The fact that so many people videotaped their first attempts at using Smart Summon, and crashed their cars, is telling. If Smart Summon were really very very good relative to humans, the first attempt would have had an almost vanishingly small chance of an accident.
I invite you to check my math, and I will check yours. Maybe we will both learn something.
