Radar tells me their closing speed, if they are slowing and how far away. Then I decide to say a prayer. The change of light pattern is incidental.

Quite so, which is why our village 20mph zone covers the whole residential extent. Of course, enforcement is another thing..

No, that's very doubtful while proper testing would be fully destructive.

Get a decent brand bearing such as NTN or SKS.
6309 denotes the size
2RS denotes the seal - https://www.astbearings.com/bearing-closures.html
Search NTN (or SKS) 6309 2RS ABEC 3 (or ABEC 5) and buy the cheapest.
I've never seen chrome plated bearings so assuming they are not which i highly doubt because that would be stupid Chromium steel is stainless steel.
Won't be chrome-plated, it will be chrome steel alloy. I'm not sure what the difference is, as you say stainless is, well, a chrome steel alloy
I doubt it will matter much, but the chrome steel GCR15 (the cheaper one) seems to be a Chinese grading which might explain the cost difference
PS, this was just from quick googling, not an expert...
