does it really know what the speed limit is?
apple maps in Oregon is frequently wrong about speeds - there are rural routes near me that are 55mph, that apple labels 25mph and refuses to change.
- genocidicbunny 2y agoProbably an artifact of being California centric. Afaik, California has an implied speed limit of 25mph (or is it 35?) when there's no posted limit. Oregon defaults to 55mph on most roads with no posted sign.
- cogman10 2y agoOregon specifies different speed limit for different zones (as does Idaho). The defaults are based on where you are driving.
- tadfisher 2y agoCorrect, see section 102 (page 2): https://www.oregon.gov/odot/Engineering/Docs_TrafficEng/Speed-Zone-Manual.pdf https://www.oregon.gov/odot/Engineering/Docs_TrafficEng/Spee...
- cogman10 2y agoMy car reads traffic signs to try and tell me what the speed limit is, it's wrong ALL THE TIME. The problem is signs that say things like "55 after midnight" or "65 for trucks" are interpreted as "55" and "65". And when it is relying on mapping data, it's not uncommon for it to mistakenly think I'm on a frontage road because the GPS/map is off by enough.
- wlesieutre 2y agoMy car doesn't have that, but in a rental Toyota it didn't understand "School zone 25 when flashing" only applied when flashing
- jeffbee 2y agoMy Honda frequently reads out god-knows-what as speed limits. 70 in school zones, 110 MPH somewhere. I think it sometimes reads gas station prices as speed limits.
