What causes the disagreements bout DUIs is the hysteria connected to em, just like COVID.

And the fact that .gov has an obvious monetary/political interest in DUI prosecution, and has set ridiculous standards for what is "drunk".

Shouldn't matter if its a first time, or 15th.

The danger to other motorists is the same, which is to say, minimal.

Only important thing is the actual impact on others.

DUI like the one described in the OP, should be little more than a speedin ticket.

DUI that involves a wreck (caused by the DUI'er), first time or not, go to jail.

Wreck with injuries = more jail.

Death = Even more jail.

The penalty should be associated with the damage to others, not the hysteria.
