"Most of the Tririum chargers seem to be unreliable, and parts take forever from USA." That is an interesting observation, I assume you mean Tritium chargers, they are designed and made in Brisbane and exported around the world. They claim to be the worlds most reliable charger, maybe they aren't.
Elon has said we won't get the Cybertruck, I take this as good news because it probably means that Tesla has a smaller ute in the pipeline that will be more suitable for all markets except the USA.
The Leaf battery has a much longer life now than in the early versions, the warranty has been 8yrs/160K km since late 2016, I just assumed that it had scored active cooling back then as well. Does yours reduce performance if the battery temp goes too high.
