Some great posts in this thread.
Absolutely agree with those saying we're over-reliant on cars. Not just cars in general, either, but larger vehicles than we actually need. Big SUVs that only ever get driven in urban areas, as an example. I'd love to see the government track the average size of vehicles used on the roads and establish a target for reducing that average size over time.
Unfortunately, the most recent VED changes did the opposite and almost completely removed (other than for full electric / hydrogen) the incentives for buying vehicles that produce less CO2.
Oh don't get me started on SUVs! All the transport problems in the world and the car manufactures said: "Do you know what we need? Bigger cars!" Car parking in Brighton would be greatly improved if they banned SUVs as we could get more vehicles into the limited spaces*. If they can't do an outright ban then just reduce the width of all spaces in all car parks in Brighton by six inches.
And I know this is a regular topic that we do to death every couple of weeks or so, but why the centre of Brighton is 100% pedestrianised I haven't a clue. Other towns and cities do it, indeed I think Brighton must be one of the few places that still allows cars to drive round roads like Ship Street. The only development we seem to get is expensive tinkering like the Valley Gardens project. What problems has that solved?
And to get back (vaguely) on topic, the only time in my 64 years I've been involved in an RTA with an injury it was caused by a bike. I was a pedestrian walking (on the pavement) up Tottenham Court Road when a cyclist hit me at speed. Despite the fact that 100% of my experience is that cyclists are dangerous lunatics I'm prepared to accept that that isn't where the main problem lies.
* I appreciate that some might say that getting 'more vehicles' in isn't itself a solution, but where I disagree with some on this thread is that not all car driving is bad.
