Direct copy and paste from the Pico Product Website:
This high-quality general purpose oscilloscope probe has a 60 MHz bandwidth. A two-position slide switch allows attenuation of either x1 or x10 to be selected.
This probe is particularly useful if you want to probe CAN bus and FlexRay signals.

Unless you are looking at Flex Ray, you don't need to use it. Flex Ray signals can exceed the bandwidth limit of the standard test leads so then you need the 60MHz probe. Standard test leads are fine with CAN.
standard oscilloscope probe with a bandwidth of 60mhz
on a standard scope ie electronics field they have a square wave output the tuning screw is used to correct the sample waveform to a perfectly square waveform on screen for correct calibration
also available in various bandwidths and higher attenuation ie 1:100
