I'd hesitate to say UK PT is bad compared to the rest of Europe. Within the smaller cities maybe in terms of relying on buses rather than light rail or metros -but even then the bus network is extensive, safe and frequent, and many senior folk and school kids rely on it as they travel for free throughout the country. For example a city the size of Edinburgh (pop 500K) runs 700 buses over 68 lines, inc 12 night lines for just one of the companies. My hometown of 30,000 has 18 bus routes and two train lines.
Rail is very extensive -16,000km of passenger route of which 37% is electric- this a national map for an area smaller than Kansas, and only showing the major stops (not the thousands of village stops in between). It has 20% of all passenger routes in Europe and is the world's 5th largest ridership (UK is the 23rd most populous country).
Any large areas not covered are mountains, moors and national parks. -The one failing is price, ever since the wonders of privatisation from Maggie Thatcher (the 20th century saw the passenger rail routes reduce by a third, although ridership has climbed multiple times, and seeing a renaissance).

It's true though they definitely drive more and rely on cars more in the provincial towns, but there will ALWAYS be a rail, bus and coach option for the townsfolk. Every tiny village and hamlet will have a loss-operating bus route as per civil right.
