The answer to why ICE are just now appearing to improve efficiency is because there are new technologies at play and market acceptance for higher costs to gain higher efficiencies.
The Volt was a car ahead of its time.

Isn't it better if we can use the Oil for all the other stuff that we are using it for instead of wasting it out of the cars exhaust?
Our world is far from being independence of oil and it will take a long time to replace everything with alternatives that we are using the oil for today.
We are using Oil for our plastics, clothing, furniture, insulation, kitchenware, food production, construction
Isn't it better to keep the oil "cheap" for those alternatives instead of wasting in our cars to propels forward.
For example in food production we are using fertilizer that depends on petroleum better to keep it for that then for something else.
If oil is a super finite resource although i believe it is more likely to be more abundant then they say but just that it gets harder to extract and to get to more oil we have to use more brute methods to extract it from the hard to reach places instead of keeping those oil wells/springs that we have for better use.
Diesel have gotten a way to bad rep i agree on that diesels are a proper good options especially if we can get HVO on a larger scale then that would be preferable.
Even if current generation of batteries aint optimal for density then the current fuels we are seeing far more improvements on that tech then we have seen in the last 100 years of petrol/diesel. And EVs are far more efficient compared to regular cars.
While Petrol/Diesel cant be reused out of the engine we can reuse batteries even when they go "bad" we can still use them until needed to be scrapped and recycled.
Again i am a strong believer that oil will be with us for a long time and i don't think we cant replace everything oil based in the next 100-300 years. But cars can be run on alternative fuels and any transportation for that matter.
Imagine if we could get large ship/vessels to run on something else then having to fill up their tanks with loads of different fuel's depending on where they are on the world oceans due to different regulations for different zones. If that isn't a waste then i don't know what.

The ICE can be more efficient, look at the Prius. It is on par with the average EV efficiency when measured as mile driven per pound of CO2 produced in a mixed power grid. People don't buy those Prius' is the problem.
Don't make what people want to buy? guess what... they won't buy it. Mandate it? Many still won't buy it.
Efficient ICE's suck to drive. Efficient EV's suck to drive. People don't want cars that suck. People don't want cars that are hard to "fill up" either. I suspect the powers in charge will mandate themselves into a corner and have to "punt".

Correct but also incorrect you are talking about people who more or less, wants cars to be performance orientated then anything else. Those are a minority i can only speak for those in my social ring and around that loads of them they couldn't care less if the car "sucks" to drive as long as it looks fast and takes them from A-B but that doesn't make EVs suck in terms of driving experience because it doesn't but to be fair i agree today's EVs are way to heavy to be considered "enthusiast" car or driven on the track but that will change especially with newer batteries improving on the weight and range in the coming 5-30 years witch isn't a long time they will from now on double or tipple in range capacity in some cases, while reducing weight at the same time and improving charging times.
But for the average Joe who likes his/hers car to look fast but doesn't really care on how it drives today's EVs are more then well enough, as long as they don't make them all look like spaceships from the future. Thats why the i4 m50 is going to be one of BMWs best selling "M-Product" lets not mistake that for a proper M-Car thats a different thing.
