288 miles from Spokane to Seattle. Roadster at 65 mph: Range 200 miles. If I use my 240v 40a UMC I get about 30 miles per hour of charging. Keeping 20 miles in reserve for detours I'd need to obtain 100 miles somewhere during the trip. That's just over 3 hours of charging.
If I drive 55 and only keep 10 miles in reserve, I'd need to obtain 288-245 = 43 miles, or just over an hour's charging, but I'd be scared to cut it that close.
Someone told me there is one charging station between here and Seattle. That, also, is problematic, since anything could happen even on the day of travel. And I do not have a smartphone, so once I leave home I cannot check unless there's a phone number to call.
If there were a few Tesla HPCs along the way, decreasing the chances of getting snookered on the road, and providing 50 miles, rather than 30, for an hour's charging, I might consider it. Probably not otherwise. And it's still a good 5 hours of driving, each way, plus charging time. Plus an overnight in Seattle, and dealing with Seattle traffic once in the city.
I'd rather pay mileage for the ranger to come here. But a service center here would really be nice. If Tesla wants to go mainstream and compete with Nissan, which has several dealerships in town, they'll need to have service centers in every city this size, especially by the time they're trying to sell a mass-market family car. Otherwise they won't even be an asterisk below Nissan's sales numbers.
