To be fair, most cars in the UK are 2.0 litres and under, so you do not really notice.
But on the other hand, it costs me $270 AU to park outside the front of my house, $20 AU every time I pass into central london, and insurance is roughly $2500 AU a year.
Of course, you could opt to use public transport which averages out at $20 a day for a one hour journey to move 10 km.
On an aside, I was in Madrid the other day. There are 4 million people and 3 million cars in that city. NUTS.
