I commute on this section daily. My experience is that at earlier commute times, you get a couple of idiots, but most folks stay between 60-70 MPH. It's the non-commute times that folks really open up - I've been doing 70 and have been passed like I was sitting still (once by a cop, who was not on duty - called the city on him - no lights, no siren, no nothing but a white streak). I've witnessed donor cyclers riding wheelies at well over 70 mph.
Paseo is three lanes in each direction, and except for a big dog-leg, mostly straight.
I would imagine that a professional race car driver (and alcoholic) clocked at 110 who blows a .16 (or whatever it was) would be just as safe as an average Joe going 70.
