Increased penalties for using a mobile phone whilst driving

The government plans to increase penalty fines for driving while using a mobile phone from £100 to £150 and to increase the number of penalty points from three to four. Does anyone think this will make any difference to the number of offending drivers? The Department of Transport found that when the penalty was doubled from £50 to £100 in 2013 it made 'no discernable difference' to the number of offenders so why would a similar increase have any effect now?

Personally my idea of a crackdown would be an immediate 12 month ban and £1000 fine for a first offence. What do others think?
