You are simply accepting that high taxes are a good reason for high fuel costs.
I reject that notion categorically. High taxation is a function of inefficient and likely corrupt government.
There is absolutely no shortage of oil, there is in fact a glut. Remember a year and a half ago when oil futures went negative? You probably don't because it wouldn't significantly affect your fuel costs because your fuel costs are predominantly taxes. You accept that, we (I) do not.
The perceived need to shift from carbon based fuels is entirely a scam to shift money, that's it. Appeal to feelings, claim "science" and use both to further fleece the population.
I'm sorry I didn't see that you were from Luxembourg, I for what ever reason thought you were from GB. I ask because I think you lack perspective on how it is here. For example a quick search says the square mileage for Luxembourg is 998. The county I live in predominantly is 593, and the state is 268,000 square miles. If I travel to my second address it is a little over 4 000 miles one way, and the square mileage of that State is 664,000. Just my commute to work exceeds a trip completely across Luxembourg.
I don't want to get in to politics here. Does not matter if I live in what is a small country. In EU it does not mater at all, you travel freely and your business, work or pleasure takes you to whatever place, and it is still a continent, even a if bit smaller overall. I also lived in Romania, Germany, Belgium and for a short while in France. I can make very easy assumptions about you, but I am not. I have visited US as well, not all of it of course.I can't pretend to know it like the back of my hand. That is not the point. You assume because where I live, in this small country that no one drives as much as in US. It the wrong assumption. I have colleagues who don't want to or can't afford the high rents in Luxembourg and they commute even 150 miles round trip to come to work. I am actually looking to buy a small house in Spain, for retirement, they are very cheap there compared to here(In Luxembourg for 600k euro you buy a broom closet with a garage maybe , in Spain for 140 k you get a house with a pool and an orchard..) , . climate is great and so are the spanish people and the food..awsome..and this second house will be aprox 1600 miles from my current one. So yeah, here you work in Norway and have a second house in Greece, or Portugal or wherever...it is actually nothing extraordinary about it.. S
o you second asumption is very wrong as well..
Taxes -- Actually Luxembourg is a tax heaven in the middle of Europe, probably most taxes here are lower than the lowest tax state in the US.
I don't mind paying taxes anyway, when they are spend wisely, I like good healthcare, I like my kids to go to good schools, I don't mind helping others in need. ( in a public school in Luxembourg a primary school teacher brings home about 6200 US $ /month net pay, that is after all the taxes are paid.. )
I am not saying that high taxes are good or the trend of downsizing engines is the best thing ever.
I am saying big engines will be gone - it is happening . There are many ways to skin a cat. In US they can't put high gas taxes because it is political suicide, but they can put a cap on emissions to manufactures so the V8 will be gone in 99% of the next gen vehicles. It is already done. Ford is paying each year Tesla a small fortune in CO2 credits, this will reflect in the price of their cars, so they will do something about it. Electrification will happen even if you don't approve it or like it.
And even tough i want to avoid politics,politics are behind of all that is happening. Right now, if you really care and want to help the environment, you stop eating beef completely ( not all meat, just beef) and keep driving your 5.7 hemi just to commute and heating up with coal or what ever and you will be greener than 99% of the people who bring the small textile bags at the supermarket thinking they are green.
They have a bloody eco shower head, and if you take a bath you are a criminal, than they eat 1 hamburger - 400 gallons of water are consumed to make it .
And yet I don't see the a 100 % tax or duty on milk, or on cows.
This is how I know the most of it is just greenwashing and motorists and car companies are just easy targets.. When I will see 1 euro tax/l of milk like for gas and a kilo of beef at 50 euro I know this people are serious about climate change/environment and hats off...
I have a small hybrid car for every day use because it is ok enough for what I do with it and is very cheap to run, mpg in heavy city traffic is unbelievable .I don't keep it because I think I will save the planet or is a joy to drive.
Plus it is very stupid in policy in Europe to force this green trend when most of the world and biggest polluters like China, India don't do anything. Even if in 10 years EU is carbon neutral and makes itself bankrupt in the process, the impact will be negligible overall..
Sorry for the ramble..
My point is this one, like the topic says, even if the prices of fuel doubles, for what ever reason, politics, oil production crisis, you can adapt, like it happened before. It is how Japan entered the US car market in 70's during the big Oil shock when OPEC was formed.
