Hey, that's my opinion. Sorry.

I think what's needed to consider is the poster's country of origin when they're comparing traffic to what we experience in the U.S.
I'm sure other than Aussie land trains no other group is going to get your issue with floating blinking lights not tied into the rear of a vehicle.
In the U.S. our standard operating procedure is for marker lights to be normally on the side of large vehicles like tractor-trailers.
Our yellow side reflectors (per our Federal reg's) are part of the very front corner of vehicles as well.
Just an issue of perspective,,,
