ok i got pulled over in my protege5 automatic about 4 months ago the cop said i was doing 60 in a 35 ok my question does any body know if it is possible for my car to go from 43 mph to 60 in 300 feet well the reason im asking is because he told me he first spotted me doing 43 mph and then pulled out of where he was and with in 300 feet said i was doing 60 mph. i was only doing 50 but i need proof from something like numbers ppl have tested and stuff to show the court that thats imposibel for that car to do that so i could not have been doing 60 please no flamers ok i need yalls help. i know some one or maybe all of you are going to tell me why didnt you just search well i did but i couldnt come up with anything please help me guys im begging you!!!!!!!

no i don't think its possible even with a few mods. i will explain. i went to the track(have my slips still) and to go 16mph((from the 1/8 mile marker(64mph) to the 1/4 mile marker(80mph) took me 6 seconds)) In six seconds time i covered 1/8 of a mile which is equivalent to 660 feet. granted this was from 4-5 gear but i was racing so this was the shortest distance i could cover in the least amount of time. i don't have trap speeds for anything under 1/8 mile but here are my distances and times which you might be able to use to calculate speed at that distance. hope this helps.

r/t....0.538
60'...2.461sec
330'...7.102
1/8...10.937@64.33mph
990...14.135
1/4...17.038@80.14mph

Also, the p5 stock, based on car and driver took 9.2 seconds to hit 60mph.

i figured it out. there is no way you could have gone from 43mph to 60 mph in 300 feet with a stock p5. i will explain. my quickest 330 foot time was 2.9 secs. this 2.9 sec was from the 990ft marker to the 1/4mi marker a total of 330ft. but in order to go 16 mph (nearly your 17 mph change in speed from 43-60mph) i needed 660 feet. these 660 ft were actually accomplished in the quickest time(1/8mi to 990ft gave me my second quickest 330ft time of 3.2 seconds). the acceleration for the p5 is quite constant(on average about 4-5 mph every 1.5-1.8secs and 140-180ft covered in that time) and therefore for me to go from 60-64 mph took 1.7 secs based on car and drivers 0-60 of 9.2 and me hitting 64 at 10.9sec.also when compared to aforementioned 330 foot times and speed they are very close. in that 4 mph and 1.7sec you would have covered aprox 150ft(give or take 10ft) which is nearly half of the 300ft he said you covered and yet you have only gone 4mph. seeing as from the 330ft to the 660ft i was in 3rd gear and the car will be in 3rd gear when you hit 60mph the car cannot acquire 17mph from the 330ft marker(7.1sec) to 60 mph(9.2sec and around 480ft) in just 2.1sec. that means you would have accelerated 17mph in under 200 feet. not going to happen when it took me no less than 140 feet to go 4mph.
i think im done now

U have to remember that all those were done in a manual. He has a automatic which takes almost another sec added onto the 1/4 mile time. So do the math, it's not happening....
