One need not accept a Gett unless it is from someone who you may marry according to the Torah, because otherwise the kiddushin was ineffective in the first place. So in Israel you should make sure to reject any driver who is not of the same gender as you.
(Note: this may be misinterpreted and you should do it at your own risk)
There is another possible issue, which is of shelichut. If someone else sends you a Gett, you may be forced to accept it if they could marry you mi'deorita even if the driver is of your own gender.
I'm told there's a new app called NoGett which forbids shlichut in its terms of service, sorts by gender and even has Kohen and Kohen Gadol settings for leniency. A baal nefesh should be stringent to use this new app.
