People take Teslas on road trips. I run up and down California and have already put 9500 miles on my Model 3. The long range combined with AutoPilot makes for a relaxing 340 mile drive in less than 6 hours. One 20 min stop, for an espresso in the Tesla Supercharger 40-stall plaza and I'm back on the road. Cost is $8.50 (espresso extra).
It will be awhile before Jag can offer an EV that can be your only car. Tesla is already there.
340 miles driving plus a 20 minute stop, in under 6 hours suggests a cruise at 60mph. The Jaguar, by all accounts, seems able to do this.
If that is your criteria for it being an only car, then it seems to me that Jaguar, like Tesla, is already there.
Of course, for some trips, it would require an extra 20 minutes, if you were limited to 50kW DCFC. But that is also true of Teslas - or no-one would ever buy or use a Chademo adaptor.
Footnotes:
Claimed realistic range : 240 miles.
Actual ranges achieved by journalists:
291 miles from 99% SoC, Top Gear Magazine, driving from London to Land's End (They added 10% charge during the trip, and arrived with 11% charge remaining).
200-205 miles, MotorTrend cruising at 70-75mph into strong headwinds, during the Low Countries portion of their London to Berlin drive.
It'll add 96 miles of range in 20 minutes at any charger of 100kW and up, and of course, there are 150, 175, and 350kW CCS chargers live on US and EU roads now. (Their official statements are "163 miles added per hour on 50kW", and 0%-80% in 40 minutes at 100kW and up).
