Public transport across most of the UK is an unreliable joke, I don't know of anyone that wants to drive (sit?!) in rush hour traffic, but they have no option as local job opportunities are virtually non-existent.
The government should offer incentives to businesses to relocate out of the cities nearer to their workforce and offer flexible/home working. Instead, they look at taxing people who have no choice but to drive at peak times to overcrowded cities.
