If the drivable platform has a network, you could use something like this: https://www.digi.com/products/models/aw02-g300 - i've never used the USB one, but the RS232 ones work great. theres probably cheaper alternatives as well. Another option might be put a raspberry pi (4, 5 or zero - with adaptors), connect it to the teensy and install software called virtualhere https://www.virtualhere.com/. I've used virtualhere on another project and it worked fine. you'll have to hotspot to the RPI or do some other networking. If you get something working, let us know!
