It's not "People sink vast amounts of time and money into their cars, they're aspirational status symbols. The UK loves it's cars.'"
It's because in most of the UK, public transport is absolutely crap, and cars are pretty much essential to having a normal life.
Not everyone lives in London and a handful of other big cities where public transport is cheap, reliable and with a useable timetable!
I hate Rishi, but he's tapping into the majority of people who are against the "war on motorists", just like Boris tapped into the forgotten Northern towns.
My son has just bought his first car. He's not remotely interested in cars, but on his first trip home for his first weekend home after starting his new job just 100 miles away (Northern city), the last train of the day to get him home was cancelled ("last" being 7:15!!!! so way too early!), and the alternative route offered would take 5 hours with 4 changes instead of the two hours direct route. That was after two weeks of buses being late/cancelled at no notice, meaning he'd been late for work on 4 days out of the first 10, despite being at the bus stop at 8am for a 20 minute bus ride on a service allegedly every 15 minutes (but in reality they turn up when the driver feels like it). He also wanted to join a 5 a side football team that played at a sport centre the other side of town, just 8 miles away - he can get there by bus, but it finishes at 9pm and there are no buses back "so late!!. After just a month, he's had enough and is now driving instead of relying on spectacularly useless public transport!
Most motorists aren't "petrol heads", they drive because public transport is too unreliable, too expensive, and doesn't operate an adequate timetable!
I hope it doesn't mean Rishi gets in, but it may increase awareness and may persuade other political parties to drop the war on motorists!
