Plenty of them here in G, Dave. G/TW-004, G/TW-005, G/SE-013, G/SE-005, G/SC-005 et al.
Of course, it is necessary to get out of your vehicle and carry your station away from it, and set-up and operate entirely independently of it in order to remain with the SOTA rules.
Some others only have the tiniest of walks from the car park to the summit: GW/NW-070, G/WB-005, G/CE-005, GW/MW-029, GW/MW-037, GW/SW-036 et al.
It is probably still possible to carry the bigger and heavier gear these short distances for a SOTA activation.
CW for SOTA activating is considerably easier and less demanding than CW generally. You can be very QRSS (slow), and need to have only the most limited vocabulary. Worth considering, whether used conventionally, or in the style of a digital mode. 5w CW from an FT-817 and a resonant efficient aerial will get you all the same DX as 100w SSB from an FT-857. Don’t automatically rule it out as an option.
