I'm not defending Ford or VW, or PSA, or Renault, but let's not forget that the market for EV's is solely due to legislation. Without that they may have existed, but only as a niche curiosity - at least for the foreseeable future. All those manufacturers survive by selling what the market wants to buy, and the market still wants ICE-powered vehicles.
Let's also not forget that absent the subsidies and tax breaks Tesla has enjoyed, it would have failed long ago. All credit to Musk for exploiting the opportunities those subsidies opened up, but to think they weren't (and aren't) instrumental in the viability of that business is extreme folly. The legacy auto manufacturers don't get those subsidies and live or die on good old profitability.
And remember also that while EV's are the legally demanded future in the big western markets, there is still a substantial market for ICE-powered vehicles elsewhere, so extant auto makers effectively have to create a new product line alongside those that already exist, at least in the medium term. In that respect they are in a much worse position than a startup as they either have to juggle repurposing some of their existing manufacturing capability from ICE to EV's or face massive write-offs in the future.
