I don't know why Tesla are reducing prices in many markets.
I'm not persuaded that there's a general lack of demand at current prices. I'd personally like to see smaller price changes as & when, with customer getting best of order & delivery price (as I did).
Currency, more cells, glut of chips, JPR007's Valley Of Death, huge ramp up of car production, Inflation Reduction Act (USA), NEV changes (China), recession, car interest rates, Berlin, Texas, 4680, LFP patents expiring outside China.
One thing that has occurred to me, if I was selling competing cars in USA, I'd be happy for IRS (tax people setting subsidy criteria) to set Model Y limits at $80,000 instead of the lower limit & thereby encouraging Tesla to sell at higher prices.
Edit $70,000 to $80,000
