I have to totally agree about the position of the cupholders on top of center console. I once bought a peach milkshake and placed it in the cupholder. Then, I rested my arm and jammed the straw through the cup spilling all its contents all over my treasured Tesla. Very poor design. I have 2017 MX.
The present cupholders are an abomination that should be addressed asap. They essentially have no adjustment whatsoever. They are positioned too close together as the OP already stated but they also need to be deeper and further forward. Basically get them off the armrest to somewhere/anywhere else.
