why or why not gm should go all ev

Why should they?

Because battery technology has advanced enough to make them practical in all of the use cases that petroleum vehicles are currently practical in? This is probably years away.
Because they figured out how to mine the necessary ingredients for batteries without leaving an environmental disaster in their wake? This is probably years away.
Because they figured out how to mine the necessary ingredients for batteries without leaving an humanitarian disaster in their wake? This is probably years away.
Because the electrical grid in a majority of countries where GM has a market presence are sufficient to charge all of these electric cars? This is probably years away.
Because various factions say it is our destiny while the same factions have no actual solutions for the above issues? If they could predict future innovations so accurately, they'd be able to lay out an exact timeline to accompany their predictions, including near events to accomplish that would bolster confidence in their prediction abilities.

Why shouldn't they?

Because battery technology has not advanced enough to make them practical in many of the use cases that petroleum vehicles are currently practical in? This is probably years away.
Because they have not figured out how to mine the necessary ingredients for batteries without leaving an environmental disaster in their wake? This is probably years away.
Because they have not figured out how to mine the necessary ingredients for batteries without leaving an humanitarian disaster in their wake? This is probably years away.
Because the electrical grid in a majority of countries where GM has a market presence are grossly insufficient to charge all of these electric cars? This is probably years away.
Because various factions say it is our destiny while the same factions have no actual solutions for the above issues? Yes.

Moved thread from the "Chevrolet" forum to the "GM Electric Vehicles- EVs" forum.

well said. I think the push from all sources either government or whoever is to fast. More time is needed to create the infrastructure to facilitate the full change to ev.

The people pushing this crap are all making big money from the push. These same people do not care about you or me they care about the money they can make.
They could care less that we don't have the grid to support even 10% EV.
The bottom line is they do not care.

I see the practical side of EVs.

Let'* say it'* an EV with a 250 mile range and someone uses it to drive ten miles each way to the office. Let'* say the same someone doesn't care about anything besides this. It wouldn't need that much charging, might just plug it in every Friday night in the garage. Who cares if it is on a 110V outlet and takes all weekend to charge? It'* not getting used again until Monday. Now it acts like a glorified golf cart. Does its job day in and day out, and occasionally needs tires. No oil changes. No warm-ups. No not warmed up enough. No check engine lights. No half-dozen different fluids trying to get past their seals. Etc.

I can totally see this.

The screw comes when the battery gets old or damaged.

Yes, in the meantime, there are some shenanigans getting things repaired. GM, Ford, Stellantis, Honda, Toyota, Nissan, etc. have all done similar things, give or take the occasional $20,000 battery replacement cost.

It'* not for me, and the cost of entry is still ridiculous, but I can see the use case for the right owner.

In the meantime, the folks with internal combustion vehicles can continue to fill the other 80% of use cases.

IMO, EV'* have their place but NOT 100% for all. When cold weather hit my friends Bolt went to 145mi. on a full charge. Became an issue when one Sunday he had to go 70 miles one way and back home the same day excluding any other detours. Ford'* 1/2 ton getting 88 mi on a charge pulling a 4500 lb trailer makes a weekend camping trip a disaster. Can't amagine the power source for a gravel pit or Quarry. I could go on as most of you all have already mentioned. Again, EV'* have a place, but not in all places.

Scumbag flesh peddlers not welcome.
