They probably infer your vehicle type from acceleration data
- gambiting 7y agoHow would that be possible? My sister has a new VW Polo with a 1.0L 65bhp engine, the official time to 60 is a glacial 16.5 seconds. I'm sure its acceleration profile would match that of a fully loaded HGV.
- 2_listerine_pls 7y agoThe time to turn, the time to break, way of turning lanes, all of it could be used to infer a vehicle type. I am not saying they do it, but it's likely.
- petre 7y agoIt's quite error prone. I doubt they do it. Also deriving acceleration data requires sub second speed sampling. This needs to be done on device as it sends too much data sampling over the wire otherwise.
- seattle_spring 7y agoIf this information were used to infer vehicle size, Google would assume everyone in Seattle is driving an 18 wheeler.
- Piskvorrr 7y agoYou could do that, theoretically, from several days of driving, with false positives and false negatives galore. Or you could ask the user...I know, not data driven, boooriiiing, and requires one more interaction.
