monitoring

Hi, has anybody checked the accuracy of the tyre pressure figures shown on the LCD screen in the car? That is, by actually measuring the pressures at the wheels and comparing. I'm wondering whether the values shown are more of an indication, rather than being deadly accurate.

Wondering if anybody else is having any issues with the Blind Spot Monitor. The drivers side works perfectly but the passenger side works intermittently. Sometimes you get the display and at other times nothing. Wondering if it's a big deal to repair or replace.
