Here's an unremarkable drive-up summit in the mid-Willamette Valley west of Salem.
 

Camano Island is a 1-point summit accessed via a short and nearly flat elevation gain hike, or drive-up due to larger activation area.  Thank you Josh WU7H for blog comment about drive-up option, and difficulty trying to chase this summit.  Stopping on side of N Cross Island Rd just North of the summit appears to be one drive-up option (see picture below).

I was looking for a reasonably tough snowshoe that could be accomplished in a day, and with few bonus point opportunities, and only so many sno parks, I kept coming back to my favorite mountains from last year. I decided to give this a try, and all things considered it went very well.

Cole Mountain is a drive-up in the Coast Range south of Highway 26 off of Highway 53. The road is passable in any passenger car and it's a radio quiet spot.

We might call this Peterson Summit rather than Peak 1700 - it's a drive-up in the Coast Range about 20 miles north of Tillamook and 20 miles south of Cannon Beach. The road is totally "Prius-able" (passable in a passenger car).
