Speed sensor out? Wrong mph?

Hey guys i have a quick question, Is it me or is it everyone who is super low having this issue? Every time im on the freeway i feel like im going the wrong speed? Like if i have my speed set at 75 cars are passing me like im doing 60. I had my gf drive with her stock 4runner and she said she was doing 75 also and was a car or so ahead of me. Is there a fix? Please help!

Thats how low im riding. Well the front raised cuz of the grass.

possibly because it is lowered. dont quote me on that tho, cuz i had a slammed s10 and was running stock wheels with smaller tires and it would say i was going 75 but i was really going like 65

what size are your tires? if you have a smaller overall outer diameter than stock, your speedo will indicate faster than what you really are doing.

Your speed sensor is fine. With 255/35 19s the speedo error is about 4% so 75 MPH is 72 MPH.

Varying times of the day, people are driving quite fast, I've been passed on the W-91 by packs doing 80+. You are just one of those Lexus drivers out for a slow Sunday like drive. Now of course you are in the #1 fast lane right?
